Standard Business Terms and customer information
I. Standard business terms
§ 1 Basic provisions
(1) The following terms and conditions of business apply for all contracts concluded with us as the supplier (preigu GmbH & Co. KG) via the websites AbeBooks and/or ZVAB. Unless otherwise agreed, the inclusion of your own terms and conditions is explicitly rejected.
(2) A ‘consumer' in the sense of the following regulations is every natural person who concludes a legal transaction which, to an overwhelming extent, cannot be attributed to either his commercial or independent professional activities. The term ‘businessman' refers to every natural person, legal person or legally responsible partnership that concludes a legal transaction in pursuance of his/its independent professional or commercial activity.
§ 2 Conclusion of the contract
(1) The subject-matter of the contract is the selling of products .
(2) If an article is placed by us with AbeBooks or ZVAB, the activation of the page on AbeBooks or ZVAB shall involve the binding offer to conclude a contract under the terms and conditions contained in the article page.
(3) The contract shall become effective via the online shopping cart system as follows:
The products intended for purchase are moved to the "shopping cart". You can select the "Shopping Cart" using the appropriate buttons on the navigation bar and make changes there at any time.
After calling up the "Checkout" page and entering the required personal data and payment and shipping conditions, all order information is then displayed again on the order summary page.
Before submitting the order, you have the ability once more to review or change any information here (you may also use the "back" button on the Internet browser), or to cancel the purchase.
By clicking the "Buy now" button to submit the order, you declare your legally binding acceptance of the order which makes the contract effective.
(4) The execution of the order and the sending of all the details necessitated by the conclusion of the contract take place via e-mail, in a partially-automated manner. Consequently, you have to ensure that the e-mail address that you have deposited with us is the correct one, and that the receipt of the respective e-mails is guaranteed. In particular, you have to ensure that the respective e-mails are not blocked by a SPAM filter.
§ 3 Right of retention, reservation of proprietary rights
(1) You can only exercise a right of retention if the situation in question involves claims arising from the same contractual relationship.
(2) The goods remain our property until the purchase price is paid in full.
§ 4 Warranty
(1) The statutory warranty rights are applicable.
(2) As a consumer, you are requested to promptly check the product for completeness, visible defects and transport damage as soon as it is delivered, and promptly disclose your complaints to us and the shipping company in writing. Even if you do not comply with this request, it shall have no effect on your legal warranty claims.
(3) If a characteristic of the goods deviates from the objective requirements, the deviation shall only be deemed to be agreed if you were informed of the same by us before submitting the contractual declaration and the deviation was expressly and separately agreed between the contracting parties.
§ 5 Choice of law, place of fulfilment, jurisdiction
(1) German law shall apply. This choice of law only applies to customers if it does not result in the revocation of the protection guaranteed by the mandatory provisions of the law of the country in which the respective customer's usual place of residence is located (benefit-of-the-doubt principle).
(2) If you are not a consumer, but a businessman, a legal entity under public law or an institutional fund governed by public law, our place of business is the place of jurisdiction as well as the place of fulfilment for all services that follow from the business relationships that exist with us. The same condition applies to situations in which you are not associated with a general place of jurisdiction in Germany or the EU, as well as situations in which the place of residence or the usual place of residence is not known at the time of commencement of proceedings. This has no bearing on the capacity to call upon the court associated with another place of jurisdiction.
(3) The provisions of the UN Convention on Contracts for the International Sale of Goods are explicitly inapplicable.

Derecho al desistimiento
Instructions for revocation
Right of withdrawal for the sale of goods
Revocation right for consumers
(A ‘consumer' is any natural person who concludes a legal transaction which, to an overwhelming extent, cannot be attributed to either his commercial or independent professional activities.)
Instructions for revocation
Revocation right
You have the right to revoke this contract within 14 days without specifying any reasons.
The revocation period is 14 days with effect from the day,
-
on which you or a third party nominated by you, which is not the carrier, had taken possession of the products, provided you had ordered one or more products within the scope of a standard order and this/these product/products is/are delivered uniformly;
-
on which you or a third party nominated by you, which is not the carrier, had taken possession of the last product, provided you had ordered several products within the scope of a standard order and these products are delivered separately;
-
on which you or a third party nominated by you, which is not the carrier, had taken possession of the last part delivery or the last unit, provided you had ordered a product, which is delivered in several part deliveries or units;
To exercise your right of withdrawal, you must inform us (preigu GmbH & Co. KG, Lengericher Landstr. 19, 49078 Osnabrück, Telephone number: +49 (0) 541 / 580 72 84, E-Mail address: mail@preigu.de) by means of a clear declaration (e.g. a letter sent by post, or an e-mail) of your decision to withdraw from this contract. You can use the attached model withdrawal form for this purpose, which is, however, not mandatory.
You can also exercise your right of withdrawal online by clicking on a button labelled accordingly (such as ‘Withdraw from contract' or similar) on the AbeBooks/ZVAB website. If you use this online function, you will immediately receive a confirmation of receipt on a durable medium (e.g. via email) containing information on the content of the withdrawal notice, as well as the date and time of its receipt.
In order to safeguard the revocation period, it is sufficient that you send the notification about the exercise of the revocation right before the expiry of the revocation period.
Consequences of the revocation
If you revoke this contract, we shall repay all the payments, which we received from you, including the delivery costs (with the exception of additional costs, which arise from that fact that you selected a form of delivery other than the most reasonable standard delivery offered by us), immediately and at the latest within 14 days from the day on which we received the notification about the revocation of this contract from you. We use the same means of payment, which you had originally used during the original transaction, for this repayment unless expressly agreed otherwise with you; you will not be charged any fees owing to this repayment.
We can refuse the repayment until the products are returned to us or until you have furnished evidence that you have sent the products back to us, depending on whichever is earlier.
You must return or transfer the products to us immediately and, in any case, at the latest within 14 days with effect from the day on which you inform us of the revocation of this contract. The deadline is maintained if you send the products before the expiry of the 14 day deadline.
You bear the direct costs for returning the products.
You must pay for any depreciation of the products only if this depreciation can be attributed to any handling with you that was not necessary for checking the condition, features and functionality of the products.
Criteria for exclusion or expiry
The revocation right is not available for contracts
-
for delivery of products, which are not prefabricated and for whose manufacturing an individual selection or stipulation by the consumer is important or which are clearly tailored to the personal requirements of the consumer;
-
for delivery of products, which can spoil quickly or whose use-by date would be exceeded quickly;
-
for delivery of alcoholic drinks, whose price was agreed at the time of concluding the contract, which however can be delivered 30 days after the conclusion of the contract at the earliest and whose current value depends on the fluctuations in the market, on which the entrepreneur has no influence;

Data protection declaration
Unless stated otherwise below, the provision of your personal data is neither legally nor contractually obligatory, nor required for conclusion of a contract. You are not obliged to provide your data. Not providing it will have no consequences. This only applies as long as the processing procedures below do not state otherwise.
"Personal data" is any information relating to an identified or identifiable natural person.
Responsible person
Contact us at any time. The person responsible for data processing is: Ansas Meyer, Lengericher Landstr. 19, 49078 Osnabrück Deutschland, +49 (0) 541 / 580 72 84, mail@preigu.de
Collection and processing when using the cancellation button
If you have entered into a contract via this platform for which a statutory right of cancellation applies, the platform provides you with a cancellation function (cancellation button) through which you can submit your notice of cancellation immediately.
When using the cancellation function, your personal data (name, email address, details identifying the contract or part of the contract you wish to withdraw from, and the time (date and time) of sending the notice of withdrawal) will only be collected to the extent that you have provided it.
The purpose of data processing is to provide you with the statutory option to withdraw from your contract and to ensure the proper processing of your withdrawal.
The platform operator collects your data on the basis of Article 6(1)(f) of the GDPR, namely the legitimate interest in ensuring the general accessibility of the statutory withdrawal function on the platform. You will receive a confirmation email from the platform operator acknowledging receipt of your notice of withdrawal.
The data is then transmitted to us by the platform operator.
If the contact relates to a contract already concluded between you and us, this data processing is carried out on the basis of Article 6(1)(b) of the GDPR. Otherwise, data processing is carried out on the basis of Article 6(1)(c) of the GDPR, to fulfil a legal obligation to provide an electronic withdrawal function.
We use your email address solely to process your notice of withdrawal. Your data will subsequently be deleted in accordance with statutory retention periods, provided you have not consented to further processing and use.
Collection, processing, and transfer of personal data in orders
When you submit an order we only collect and use your personal data insofar as this is necessary for the fulfilment and handling of your order as well as processing of your queries. The provision of data is necessary for conclusion of a contract. Failure to provide it will prevent the conclusion of any contract. The processing will occur on the basis of Article 6(1) b) GDPR and is required for the fulfilment of a contract with you.
Your data will be shared, for example, with shipping companies, dropshipping or fulfillment providers, payment service providers, service providers for order processing, and IT service providers. We will comply strictly with legal requirements in every case. The scope of data transmission is restricted to a minimum.
Duration of storage
After contractual processing has been completed, the data is initially stored for the duration of the warranty period, then in accordance with the retention periods prescribed by law, especially tax and commercial law, and then deleted after the period has elapsed, unless you have agreed to further processing and use.
Rights of the affected person
If the legal requirements are fulfilled, you have the following rights according to art. 15 to 20 GDPR: Right to information, correction, deletion, restriction of processing, data portability. You also have a right of objection against processing based on art. 6 (1) GDPR, and to processing for the purposes of direct marketing, according to art. 21 (1) GDPR.
Right to complain to the regulatory authority
You have the right to complain to the regulatory authority according to art. 77 GDPR if you believe that your data is not being processed legally.
You can lodge a complaint with, among others, the supervisory authority responsible for us, which you may reach at the following contact details:
Landesbeauftragte für den Datenschutz Niedersachsen Prinzenstraße 5 30159 Hannover Tel.: +49 511 1204500 Fax: +49 511 1204599 E-Mail: poststelle@lfd.niedersachsen.de
Right to object
If the data processing outlined here is based on our legitimate interests in accordance with Article 6(1)f) GDPR, you have the right for reasons arising from your particular situation to object at any time to the processing of your data with future effect.
If the objection is successful, we will no longer process the personal data, unless we can demonstrate compelling legitimate grounds for the processing that outweigh your interests or rights and freedoms, or the processing is intended for the assertion, exercise or defence of legal claims.
