It would be nice to put different prices for each country.
For example .. in Panama the dollar is 1: 1 so 10 dollars would not be too expensive. But in Venezuela is 1,200 bolivars 1 dollar so $ 10 would be 12,000 bolivars which is much as an average salary of that country is 40 dollars.
I explain? 100 credits to put that cost 10 dollars in panama but $ 1 in Venezuela.
