Nice idea, wrong approach.
The same product should cost the same money on any place on the globe.
Mercedes isn't offering the S Type for 1/4 of the regular price in Brasil.
I understand your motivation behind the change, to get more people to buy Supporter, but this is the wrong approach. Again, an identical product should have the same price everywhere.
You should have lowered the price for Supporter in general. Or offer a Basic Supporter Package (with most, but not all features) for let's say 15 $ and a Premium Supporter Package for 40 $ (with all Supporter features plus one or two extra gimmicks).
