Nice to give. But even more fun to get. You want to give someone a gift but you can't choose yourself or would like themselves to make the choice then the gift certificate by mail is THE solution!
You can purchase by steps of 25 € a voucher, that is linked to a code.
The voucher is sent to you by mail if you want you can send it directly to the receiver too. Than you choose "Also send to the receiver".
The recipient can then place an order from this amount the gift voucher will be substracted ( when entering the code) . So you can never make a wrong choice!
