I would like to buy some emo CDs

I live in a small city in Brazil and there are very few places that sell CDs here, I would like to buy them online but I can only find them at absurd prices. Does anyone know how I can do it to buy at lower prices or if anyone would be interested in importing? (I'm interested in more generic post-hardcore and emo CDs because they're easier to find, like MCR, PTV, Falling in Reverse, etc...)
