> no legitimate circumstances where someone would want or need to sell amazon gift cards at less than their face value.

Absolute statements like this are so hard to back up.

For instance, if you live in Cuba, Iran, Syria, North Korea, or Syria, Amazon.com gift cards are worthless.

I know I received some AmericanEagle gift cards as a promotion recently, and unloaded them for less than face value just because I had absolutely no need/want to use them.
