We recently set up an authorize.net account and love it. One issue that I'm running into is allowing overseas clients pay via our authorize.net account. We have several clients that are in the U.K and all get declined. I can turn off the AVS system and it will allow them to pass, but obviously I do not want to leave AVS disabled because of fraud. For those of you with an authorize.net account, what options can I get away with to allow our U.K users the ability to pay, but not disabling too many options to leave us vulnerable...any thoughts?
