Isn't gas expensive enough?

What am I missing?
Why would someone bid over $50 for a $50 Gas card?

I see the shipping is free on Ebay for this one.
But other auctions are like this too???

This site http://www.svmcards.net charges a minimum of $6.95 shipping plus a surcharge but can't you go to your local station and get the card for face value?

I guess being stupid can get expensive.
