Links to gift card fraud will put your Amazon account at risk, though. There are countless stories about account closures linked to Amazon gift cards bought from Localbitcoins or purchases made on Purse.io. People have even had the police bust in their house with search warrants because of them.
This is why I don't buy Amazon gift cards P2P at all. I only deal with trusted vendors like BitPay or Bitrefill.
With physical gift cards in brick-and-mortar stores, this isn't an issue. I'm much less concerned about fraud there since there is no link to my identity.
