In comparison to ebay.... Thats every store?
You said you found some that compete with ebays pricing. I say theres something a miss here.
See the problem that people don't even begin to understand is the over head cost.
When you open a store you have lease, utilities, any possible employees, up keep of shop.
Ebay. You have......... ummmm ... uhhhhh.... Gas to go hunt for items in the wild to sell? perhaps?
Unless your apart of this new trend for ebay shops where they open up a physical shop in the area of where they are located but yet its never opened.. you just plaster your items in the store front. (i seen one near me in vermont. and also one in lake george NY)... Never understood those at all.
