Amazon might now be the defacto marketplace to buy and sell online goods in the UK, but eBay believes its good surprise might just lure customers back into the world of online auctions. In a bid to make things things a little easier for users to understand, eBay says that from May 13th itll allow UK users to list up to 20 items every month completely free of charge. Listings can include any item, as long as its not a car, and eBay continues to retain its 10 percent selling and postage fee.
