Seems a good bargain. 50p each!!!
AMAZING DEAL - The price shown is for 2 top quality silicone cases. These smart and durable cases/skins help to better safeguard your valuable Apple iPhone by providing an improved grip and better impact protection in case of an accidental drop etc. This case is a superb fit for 3G and 3GS and gives full access to all the iPhone's controls and camera lens.
These cases will fit the original iPhone very well but the back of the case moves a tiny amount - still an excellent fit and its actually very hard to notice any real difference in fact !
