$5 dollars of free money isn't bad. But I wonder how much all those paper clips would cost him, and after he ships them all out will he really make anything?
OfficeDepot.com sells 100 clips for 72 cents. That's .007 a clip plus 37 cents to mail them anywhere in the country. He's looking at around 62 cent profit per clip BEFORE paypal fees. If he bought over 2000, he probably got them even cheaper.
Does anyone really think that if you bought a paper clip that he actually going to send one. Whatever they get they'll keep. It a good scam selling or asking for such a low amount that people would do it just for the joke and some may actually send the money. Whatever they get it's all profit.
