§ 3 conclusion of contract

With your order you are submitting a legally binding offer to conclude a contract with sizezero. The purchase contract is concluded when sizezero accepts your offer by shipping the goods. The automatically generated confirmation e-mail after receipt of the order does not constitute a declaration of acceptance on the part of sizezero. This e-mail only confirms that sizezero has received your offer. The transmission of the account details by email for the purpose of prepayment does not constitute a declaration of acceptance by sizezero.

The contract text is saved. The specific order details of your order can be found in the confirmation of receipt that you will receive from sizezero by email. You can view or download sizezero’s general terms and conditions at any time on this page.

The conclusion of the contract is possible in German or in English.

Consequences of the withdrawal

If you withdraw from this contract, we will have given you all payments that we have received from you, including delivery costs (with the exception of the additional costs that result from choosing a different type of delivery than the cheapest standard delivery we offer have), to be repaid immediately and at the latest within fourteen days from the day on which we received notification of your cancellation of this contract. For this repayment, we will use the same means of payment that you used for the original transaction, unless something else was expressly agreed with you; In no case will you be charged any fees for this repayment. We can refuse the repayment until we have received the goods back or until you have provided evidence that you have sent the goods back, whichever is earlier.

You have the goods immediately and in any case no later than fourteen days from the day on which you inform us of the cancellation of this contract

to be returned or handed over. The deadline is met if you send the goods before the period of fourteen days has expired. The costs of the return are to be borne by you.

You only have to pay for any loss in value of the goods if this loss in value is due to handling of the goods that is not necessary to check the nature, properties and functionality of the goods.

§ 6 Non-existence of the right of withdrawal

The right of withdrawal does not exist:

1. if you are not a consumer within the meaning of Section 13 of the German Civil Code (BGB).
2. for goods that are not prefabricated and for the production of which an individual selection or determination by you is decisive or which are clearly tailored to your personal needs.
3. for audio or video recordings or computer software in a sealed package, if the seal was removed after delivery.

§ 7 delivery, subsequent delivery

Unless otherwise agreed, delivery will be made to the delivery address you specified. Information about the delivery period is non-binding, unless the delivery date has been promised as an exception.

In individual cases, sizezero offers you that a product that is initially not available will be sent to you later when it is available (subsequent delivery). You do not pay any additional shipping costs or cash on delivery fees for subsequent deliveries.

§ 8 Exchange

sizezero is not obliged to exchange goods that are in perfect condition. As a rule, sizezero fulfills your exchange request, as far as this is possible. Sizezero can charge additional shipping costs for re-shipping because of an exchange. Your right of withdrawal (see § 4) is in no way restricted or excluded by this regulation.

§ 9 payment

At sizezero you can only pay in advance for the time being. The EU is working on a law to regulate the fees charged by credit card companies. We are a service and craft company. We currently do not want to accept costs of up to 3 percent for payment by credit card; We ask for your understanding.

§ 10 Due Date and Default

The purchase price is due immediately upon conclusion of the contract, unless we have given you a different payment term.

§ 11 dunning fees

We do not charge reminder fees. If the purchase price has not been transferred within seven days of receipt of the invoice, we will cancel the order process.

§ 12 Offsetting, right of retention

You are only entitled to offset if your counterclaims have been legally established or have been recognized by sizezero. You are only authorized to exercise a right of retention if your counterclaim is based on the same contractual relationship.

§ 13 retention of title

The goods remain the property of sizezero ug until they have been paid for in full

§ 14 Warranty for Defects and Liability

The statutory warranty provisions apply. The warranty period is 2 years and begins when the goods are handed over. Your warranty claims are initially limited to supplementary performance (removal of defects or replacement delivery).

Unless otherwise stated below, further claims – regardless of the legal grounds – are excluded. sizezero is therefore not liable for damage that did not occur on the delivery item itself; in particular, sizezero is not liable for lost profit or other financial losses. Insofar as sizezero’s liability is excluded or limited, this also applies to the personal liability of employees, representatives and vicarious agents.

The above limitation of liability does not apply if the cause of the damage is based on intent or gross negligence or if there is injury to life, body or health. The limitation of liability also does not apply if you assert claims from §§ 1, 4 of the Product Liability Act. The limitation of liability also does not apply in the event of a breach of an essential contractual obligation.
