You can buy directly from Paulo, just sent him an email hotmasterfsim@gmail.com and he will help you. But to buy anything in Brazil online, you will need a CPF, which is a number to identify each person in Brazil for tax purpose, i guess is equal to a Security Number in US. To get a CPF you need to enter in the Consulate of brazil website http://boston.itamaraty.gov.br/en-us/taxpayer_registry_-_cpf.xml it is a free service, just fill the form and sent the documents and the Government will sent you the CPF.
