ebay
Ebay is just like any other business, it has a great product, (the sellers) with one of the largest customer base anyone will ever see (the customers) with alot of people overcharging on P&P and making extra money that ebay cant touch, believe me ebay is not trying to be nice, it is raking in more money, Ebay does not care how many small "seller" it puts out of business because for every one it losses, another will take its place sooner or later Ebay will make the fees a little higher, either make charges for postage or make it so that the seller has to offer free postage on there site, all sellers will only have PAYPAL as it's payment option, WHY I here you say, Because it can.
