£0.00 on category page in safari and chrome


I have just built my first cs cart site www.vunk.co.uk but im having a few problems. As I sell wall stickers I wanted to have no price untill the customer selects the product options they want. This seems to work fine on ie8 but on google chrome and safari browsers the price shows up as £0.00 on the home page and category pages. Also any site advice would be greatly appreciated.

Kind Regards
