This jerk is a total scammer.
Read this thread and his recent thread offering to place the order for you.
Nobody buys gift cards with BTC only to sell the same gift card at a 20% loss for BTC again.
Check him out on here:

If the gift code isnt applied to your account, thats red flag #1.
Another possible red flag would be the code could be wrong, that wasnt purchased by bitcoin. That was earlier mentioned above.
Indeed this is nothing more than a fraudulent credit card scam.
He may buy an amazon gift card for photos, and might even buy one with BTC for a paper trail,
But the "I will order it for you, just pay me 20% up front" part is so faulty!
Taking a 20% loss is very fake.
Buying with BTC, and selling for BTC also makes no logic.
And in the end he is just using stolen credit cards to order people stuff, and accept BTC in exchange.
