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.

2. Contracting Party, Conclusion of Contract, Correction Options

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

2.2 Conclusion of Contract
By listing a product at a fixed price, we make a binding offer to conclude a contract for that product. The fixed price and duration of the offer define the acceptance period.

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.

To cancel a transaction, use your browser’s “back” button. In the shopping cart, quantities can be adjusted or items removed. Errors can also be corrected by canceling the purchase process.

3. Contract Language, Storage of Contract Text

The language available for the conclusion of the contract is German.

The contract text is stored in our systems but is not accessible to you. However, you may view recent orders via your Abebooks or ZAVB account under “Purchases/Sales.” The full contract text is not accessible there.

4. Delivery Conditions

Products are shipped to the delivery address specified during the ordering process.

Delivery is by shipment only. Collection is not possible.

Further claims remain unaffected.

6. Right of Withdrawal

You are entitled to the statutory right of withdrawal as described in the withdrawal policy.

7. Retention of Title

For entrepreneurs: risk passes upon handover to the carrier.

Informazioni sul diritto di recesso

Diritto legale di recesso

Hai il diritto di recedere dal presente contratto entro 14 giorni senza fornire alcuna motivazione.

Il periodo di recesso scade dopo 14 giorni dal giorno in cui tu o una terza parte, diversa dal vettore e da te indicata, acquisisce il possesso fisico dell'ultimo bene o dell'ultimo lotto o pezzo.

Per esercitare il diritto di recesso, compila e invia elettronicamente una dichiarazione esplicita sul nostro sito Web, alla voce “I miei acquisti” nella sezione “Mio account”. Ti comunicheremo senza indugio una conferma di ricezione di tale recesso su un supporto durevole (ad es. via e-mail).

Per rispettare il termine di recesso, è sufficiente inviare la comunicazione relativa all'esercizio del diritto di recesso prima della scadenza del periodo di recesso stesso.

Effetti del recesso

In caso di recesso dal presente contratto, ti rimborseremo tutti i pagamenti ricevuti, compresi i costi di spedizione (ad eccezione dei costi supplementari derivanti dalla tua eventuale scelta di un tipo di spedizione diverso dal tipo meno costoso di consegna standard da noi offerto).

Potremo effettuare una detrazione dal rimborso per la perdita di valore dei beni forniti, qualora tale perdita sia il risultato di una manipolazione non necessaria da parte tua.

Eseguiremo il rimborso senza indebito ritardo e non oltre 14 giorni dal giorno in cui saremo informati della tua decisione di recedere dal presente contratto.

Il rimborso sarà effettuato utilizzando lo stesso mezzo di pagamento da te usato per la transazione iniziale, salvo che tu non abbia espressamente concordato altrimenti; in ogni caso, non dovrai sostenere alcun costo quale conseguenza di tale rimborso.

Possiamo trattenere il rimborso finché non avremo ricevuto i beni oppure finché non avrai fornito la prova di averli rispediti, a seconda di quale condizione si verifichi per prima.

Dovrai rispedire i beni o consegnarli a Books-by-Floh, Paderborn, Germany, senza indebito ritardo e, in ogni caso, entro 14 giorni dal giorno in cui ci hai comunicato la tua volontà di recedere dal presente contratto. Il termine è rispettato se rispedisci i beni prima della scadenza del periodo di 14 giorni. I costi diretti della restituzione dei beni saranno a tuo carico. Sei responsabile solo della diminuzione del valore dei beni risultante da una manipolazione diversa da quella necessaria per stabilire la natura, le caratteristiche e il funzionamento dei beni stessi.

Eccezioni al diritto di recesso

Il diritto di recesso non si applica a:

1. La fornitura di giornali, periodici o riviste ad eccezione dei contratti di abbonamento; e
2. La fornitura di contenuto digitale non fornito su un supporto materiale (ad es. su un CD o DVD), se al momento dell'invio dell'ordine hai accettato l'inizio dell'esecuzione e hai riconosciuto che non avresti potuto recedere una volta iniziata l'esecuzione.
