a few years back a friend of mine made money from ebay without spending as penny. he would search items on ebay, (nowt in particular) and hunt down those ads which were cheap, badly advertised, etc etc on buy it now. he would then make his own listing with the help of google images and some google research then offer his own price wether it be biy it now or auction. he would then buy the listing he originally found and get the seller to send it to whoever won his 'item'. pretty dam cheeky but not actually breaking any rules or laws. made a killing. on one i think he made around 700 quid for ten minutes work on his pc. not too shabby!
