I fill everything out, then right when I click to complete the order, it redirects me back to the previous page with the error " ZIP Code does not match Billing Address". I live in the UK, not sure if that might have something to do with it, but I know with 100% certainty that I entered the right Post Code for my Shipping address (my own house) and for the Billing address, regardless of whether I choose "Same as Shipping address" or I enter the details again manually, it gives me the same error. I even tried completing checkout as a guest and entering EVERYTHING manually, but even that didn't work, it just keeps giving me the same error. I've triple checked the Post Code, so I don't know what could possibly be wrong. Could anybody point me in the right direction? It'd suck beyond belief if I missed out on the shirt purely because of a -blam!-ing website error.
