Can you make a profit on Ebay?

First thought about making money on ebay is by selling stuff as all the responses have shown. But lately I've been making money by buying. Not a whole lot 50 bucks here, 100 there. But with the great prices offered by some of the buyers here, I've been picking up lots of scrap computer stuff and all I have to do is rebox it and print a label. It is hard to win due to (I'm guessing) home refiners paying well over what the buyers here pay out. But you can win quite a few. I have the best luck with the "make offer" auctions. I got a box of 30 lbs of ram for what came out to be about 12 bucks a pound. Quick easy 50 dollar score. And best part is, I usually do my bidding at work while in the bathroom. Nothing better than getting paid to drop a deuce, except getting paid twice while doing so. Lol.
