I've been working on a website for one of my Russian clients. So far getting any payment method to work has been horrible.
So I'm glad to have heard that as from last week PayPal has finally entered the Russian market!
I've checked my customers' PayPal account and changed the settings to RUB. Also I added Russian Rubles to the store settings.
It seems to work perfectly, even though I'm still awaiting my clients reply, they are going to make a test payment.
So my suggestion is to add Russian Rubles to PayPal gateway in the future!
