Update 2018-01-11: so far so good.
Update 2018-01-13: Everything seems to be fine.

Original post:

Bought 2x Amazon de code from the seller via Paxful:

- In discussion he stated they are physical cards but when transacting, they appear to be codes (reason: no phone/camera at hand);
- Nevertheless, I continue the transaction, codes successfully entered the account;
- I waited one day, so far there is no any problem. I will buy some small stuff first;

So:
- If any other buyer wants to purchase, I would recommend to insist getting photos of cards, not code only;
- If any problem will happen, I will come back and post;

In general the communication is good and transaction is smooth.
