Brazil's national currency is the real, but you wouldn't know that by looking at its iTunes storefront. Apple prices everything there in US dollars, which has led Brazil's Consumer Protection Secretariat to write a formal letter to the company requesting an explanation. We're not sure why this has taken so long, given that iTunes came to Brazil two years ago, but in any case Apple now has ten days in which to respond or face the threat of a penalty. Other countries that've tackled Apple over its pricing policies in the past have generally failed to reach a resolution, and in some cases citizens have even been urged to take matters into their own hands.
