£300 ($495) for a 1 yr old black 16gb 3G with an applied screen protector. Cost me £9 ($15) to advertise it on Ebay, they took 10% final value fee of £30 ($50) and Paypal (which is owned by Ebay) took another £11 ($18) for allowing me to get paid. Ebay are sheisters! They charged me in total £50 ($82.50) to sell a phone!
So in the end I basically got £250 for the phone. It cost me £198 to terminate my contract and I got £52 off the new 3GS making it £222. So thats what it cost me to upgrade, £222. I hate Ebay! I can't begin to imagine how much money they must make if they made £50 just from me for one item!
