Yeah, I've got the American Viabox thing set up, but I can't put a UK billing address in, so it's obviously noticing a mismatch between the Billing Address on my card and what I've had to put the billing address in as (the viabox address), so it won't let the payment go through.
If you can grab two and your details are working then that'd be amazing
I'm trying to message them at the moment but I doubt they'll respond before they've all sold out because they're obviously totally imcompetent
