Hello Glitz before making that leap into the vast world of feebay you might want to look at this first. Also read the message boards on ebay to see whats been taking place as of late, and get some real dollar figures as too just how much that store is really going to cost you, it's not just the listing fee's but the store fee's the paypal fee's and if your going to accept credit cards theres some more fee's for the paypal payment pro acct. heres a link to where a good number of the ebay power sellers are going. http://auctivacommerce.com/
and here is a link to the list of power sellers that are opening an Auctiva store front http://www.craftcycler.com/Auctivastorefronts.html
Good Luck and hope this gives you some insight.
