"You" is any random fella who has an Amazon account and can buy GCs, and give them to other random someones.
The government doesn't give out Amazon GCs nor accepts them. I think?
...But yet they can be very interested in the movement of currency and its close analogs...
And yes, it is indeed highly likely that Amazon knows who used a certain GC code
You jest, but if you are worried about "random" people1
knowing what "random" people2
are doing with gift cards, I'm just saying that while your aunt won't call Amazon and lie saying "by golly, I didn't even buy that gift card and I'm going to chargeback unless you revoke it", "random" people1
are actually quite good at doing "random" things just like that. If they are truly "random", hey, they might not even be lying...
Sure, maybe Amazon won't ever say who or what, but are you worried more about that sort of privacy from "random" people1
or having your account locked (and who knows what else) because you've been implicated in fraud?
