Why would you spend 158 dollars for a 150 dollar gift card? I don't even understand why you would want a gift card to begin with. All it does is limit the places you can spend it on.

You speculate that they are stupid, but in all honesty if it is that obvious, then there is probably a very legitimate cunning logic behind bidding higher than the face value. People are stupid but not that stupid!

Its most probably something along the lines of a discount scheme where the purchaser would already be entitled to a further 30% off somewhere else like a marketing loyalty pool/scheme thingy.
