I'm sure it's a very good technique, but this thread is pointless then. Why does anybody care that you made some money?
So you have about $500 so far, take it to a pawn shop and put small deposits on a lot of big items. Take pictures of the items. List those on ebay. If they sell go back and buy them If they don't sell, go back and move the deposits to other items. You should be able to make it that way. You might make a lot more Just an idea good luck
