$5 admishun

i was on ebay and randomly decided to search "groupon". i was slightly surprised to see a decent amount of auctions. there were random groupons from all over the country. then i looked at some completed auctions. jackpot, i saw several auctions for groupon credits ending at huge discounts, which i assume is the same as a gift card. there was a $265 credit that sold for only $174ish. sick, so you buy the groupon credit at a discount on ebay. use that discounted credit to buy groupons. genius, you save money by saving money. whoa!

but i was thinking. a couple months ago, i bought a groupon for a restaurant called Foreign Cinema, costs $25 for $50 worth of value, basically a $50 gift card. why wouldn't this work: i go to the restaurant, creep outside, wait for a couple to walk in. "psh, hey, you, um, look, you're going to spend at least $50 here, fact. so let me help you, i have this groupon, i'll sell it to you for $40. you save $10 on your bill. cool?" let's forget how shady it looks. this SHOULD work. he saves $10. and i make $15. to be honest, he should be willing to spend $49.99 because he still benefits. am i missing something
