TopBucks charges all surfers in their local currency. Webmasters can promote us either on PPS or on Revshare, when we're cutting off the 70% for revshare the amount webmaster gets paid is being calculated based on the local price the surfer paid.
E.g. a surfer paid $49.95 for a monthly subscription, webmaster will get 70% of $49.95 (not $39.95 which is our standard US price)
