I'm kind of with you on this one Clarry, It might be different for me because I know that my ebay and PayPal addresses are the same, but I don't recall ever being asked to select  shipping address, and I always pay by PayPal (well once I had to use PayMate cos I was a numpty and didn't read the description properly and didn't realize the seller didn't offer payPal, but ykwim)
