HELBRECHT optics lets you try out your purchase! This means that you can return received goods without giving reasons within two weeks. The purchase contract is binding by your approval after receiving the goods, but no later than the end of the one month rescission period.
You may rescind your contract in writing (e.g. letter, fax or email) within 30 days without giving further reason or by returning the goods before the deadline expires. The period begins upon receipt of this notification in text form, but not before the recipient receives the goods (in case of recurring deliveries of similar goods not before receipt of the first partial delivery) and also not before we have fulfilled our obligation to provide said notice under Article 246 §2 and §1(1) and (2) of the Introduction to the German Civil Code as our obligations under §312g (1)(1) of the German Civil Code and Art. 246 §3 of the Introduction to the German Civil Code. Notice of rescission or return of the product in a timely manner constitutes meeting the deadline for exercising this right.
If the right of rescission has been exercised in a timely manner, the products and payments and any benefits received (e.g. interest) shall be returned to the other party. If you cannot return the product in whole or in part or return it only in deteriorated condition, you must compensate for the loss of value. When returning items, this does not apply when the deterioration of the item can be attributed to its examination such as would have been done in a physical retail store. In all other instances, you can avoid the obligation to pay compensation for any deterioration caused by using the product by not treating the product as your property and not doing anything that would reduce its value. Transportable items are to be returned at our risk. You shall bear the return shipping costs if the goods delivered were as ordered and if the price of the item being returned does not exceed €49; for higher-priced items being returned, if the customer has not paid for them in whole or in part, the customer shall also bear the return shipping costs. In all other instances, there will be no return shipping costs for the customer. Items that cannot be shipped will be picked up at your location. All obligations to reimburse payments must be fulfilled within one month. The period begins for you when you send your notice of rescission or return the goods; it begins for us, when we receive the same.
Excluded from the right of rescission are goods that are manufactured according to customer specification, cf. §312d(4)(1) BGB.
Buying a pair of prescription eyewear is and should remain a matter of trust!
The law generally excludes the exchange of custom products. This does not apply to us!
If something's not OK with your new eyeglasses, our FAIR DEAL applies. Our return policy even covers vision-related issues (such as headaches or dizziness). If you are still not happy with the result after we craft your product, you will receive your money back – no ifs, ands, or buts!
The FAIR DEAL does not apply if false information or an outdated prescription was provided or if you do not like your eyewear.
