I checked out StampOffers, and if I remember correctly, he charges
$.75 for a gallery image and no one uses them except him since he
is the owner so it costs him nothing.
This is, in my opinion, very poor business strategy (but he probably
isn't really in business). The competition,
ebay and StampWants don't
charge for a gallery image. He wants $.75 but no on buys them to list
their nickle and dime stuff. I mean, who is going to spend $.75 to
maybe make a a dime or a nickel if something sells. If he were to make
gallery images free, his site would look better and in all
probability attract more users, and even if he didn't charge
insertion and final value fees, get more hits on something like
google ads on his site. He could have his hobby site and probably
cover his hosting costs and make a little money too.
