one way scammers make $$ is by using stolen accounts to purchase goods and then re-sell them, but in general they have pretty much one shot before they are found out and the credentials go stale (for their purposes). electronics can be small in size, have high re-sale value and there's already a solid gray market for them, so it's a particularly valuable credential.

i'd also venture a guess that fry's has less effective anti-fraud software/defenses vs. amazon or ebay or other platforms where you can buy electronics - would not be surprised if amazon was good at catching a fraudulent iphone purchase on the first try, whereas fry's might let a lot more slip through.
