"You have the right to revoke the treaty for 14 days after receiving the goods without giving reasons.
After we received the return, we will refund the product value and, if all the ordered products are returned, the delivery costs "
The bad extra surprise is that the seller refuses to pay the shipping costs which are almost the same level as the price of the product, in the case of a shipment in Germany, because they do not consider themselves bound by the conditions set from Amazon and make me the following answer:
"I'm sorry but we are not amazon and so we do not have their terms and conditions. This is a bit like in a shop amazon, amazon soulouait us a corner of his shop without their employees."
