for me it's more of a location problem than money problem, unlike you lol
1) use onion or any free VPN, there are hundreds of them and no one will steal your payment information just like that
2) buy with crypto or your local currency a prepaid debit card with the required denomination / buy access to a grey card (if you are from Russia, there are a huge number of options on plati*ru)
3) profit. The seller gets money from the Brazilian from the Turkish card, you get the goods.
It's literally so easy if you don't have problems with money specifically
