Any chance of making these available via itunes?
I suspect internationally it is probably the most common/universal distribution platform.
A lot of people have itunes accounts and it saves us having to open another account.
If Apple’s cut is higher than other distribution mediums, then I’d pay a premium – or price the same and perhaps sell more copies.
Even people without credit cards, can buy from iTunes via vouchers which you can buy in all sorts of retail locations.
