Overseas clients, for example those with UK credit cards are unable to book online as the system now requires a US zip code. Is there a way to make credit card submission accessible to cardholders outside the United States?? This is way too limiting. Also, if a client refuses to give their zip code, i've found that any zip code added to the card information still allows entry into boulevard, and processes fine. I'm certain the added zip code feature is for added security, but does need fine tuning. Thank you
