I've been selling a lot less and using ebay more for purchases. Buyers market right now, everytime I think I find a good price on some goods to resell, I seem to find it on ebay cheaper. Still selling my classic video games through there, and pictures do help. Photobucket slideshows save me some insertion fees. I don't have the buying power to get the really good prices on resale merchandise, which is why I'm beaten so easy.
if you have a lot of items, get a store you pay less in fees in the long run unless you continue to run all your items as auctions. auctions get items sold faster however not always at the price you want best offer also gets items sold faster for BIN or store items take good pictures, with no background noise, white backgrounds work best take multiple pictures at different angles free combined shipping if you have a store, have it designed well, appear as if you are a business because basicly, if your selling anything you are a business. there are a lot of tips, id recommend picking up some books from the book store, some examples: starting an ebay business, tricks of the ebay mastermind, etc.
