Could I order two devices with one voucher and get one order free of charge?

Let's say we have a cell phone, a laptop and a 50 euro Amazon voucher.

If I log in with the same account on both devices & then redeem the voucher, I have, so to speak, 50 euro on both devices because it's the same account.

And if I then simply press order on both devices in the same second, will I receive the order twice?

I've tried it on another site and have already received an order confirmation for 2 items.

I'm curious whether both will arrive.

Vouchers are not credited to the device but to your account. You will definitely only get 50 euro credited and the other will be canceled or charged via your other payment methods. If that were possible, there would probably be no more vouchers for a long time.

I thought so too. But you don't even know how many ways there are or life hacks to, for example, order things for free, go out to eat Mc for free. Take a taxi for free, etc.

Yes, they usually only exist for a few days or even only hours. Something this flashy won't work.

I can only agree with Dersorbu, something like this will not work, especially not in the long term.
