I want to pay for a VPN service with my UK credit card but I've recently moved to Japan. On the form I can select Japan or the UK but Japan won't charge a sales tax so it's obviously a better deal that way. I would be the primary user of the VPN but family back in the UK would use it too.
I can't find any information on what to do with non-physical goods like this, normally I'd pay the local tax and (if I wasn't in a lazy mood) reclaim it at the airport but this is a tad different.
Any help or insight would be much appreciated.
