1. Scope

These General Terms and Conditions (GTC) apply to all orders placed via the Abebooks or ZAVB website by consumers and entrepreneurs.

A consumer is any natural person who enters into a legal transaction for purposes that are predominantly outside their trade, business, or profession. An entrepreneur is a natural or legal person or a legal partnership acting in the exercise of their trade or independent professional activity.

With respect to entrepreneurs: conflicting or supplementary general terms and conditions are hereby rejected unless expressly agreed otherwise.

The purchase contract is concluded with Books-by-Floh - Florian Gerlach.

2.2 Conclusion of Contract

You may accept offers for multiple products by placing them in the shopping cart (subject to availability) and completing the subsequent payment process.

2.3 Correction Options
You may identify and correct input errors during the ordering process using the tools provided by Abebooks or ZAVB.

Information regarding the right of withdrawal

Statutory right to withdraw

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.

To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).

We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.

We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.

We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.

You shall send back the goods or hand them over to Books-by-Floh, Paderborn, Germany, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.

Exceptions to the right of withdrawal

The right of withdrawal does not apply to:

1. The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
2. The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.

Privacy Policy

We use the data you provide to fulfill and process your order. Your data will be passed on to the shipping company commissioned with the delivery, insofar as this is necessary for the delivery of the goods.

For the processing of payments, we may pass your payment data to our bank where required. Your data will not be disclosed to other third parties or used for advertising purposes.

Upon full completion of the contract and full payment of the purchase price, your data will be blocked for further use and deleted after the expiry of the retention periods required under tax and commercial law.

We protect our systems through technical and organizational measures against loss, destruction, access, alteration, or dissemination of your data by unauthorized persons. Despite regular checks, complete protection against all risks is not possible.

You have the right to receive free information about your stored data, as well as, where applicable, the right to rectification, restriction, or deletion of such data.

For questions regarding the collection, processing, or use of your personal data, for information, correction, restriction, or deletion of data, please contact:
