When transferring funds from Paypal to BPD, your funds will not be transferred in dollars, but in pesos, in case that's the reason you are opening a US Savings account. One of the advantages is that the conversion rate, is the one BPD has at that moment, not some crazy Internet Conversion Rate (Like Amazon 48x1).
Yes, also ebay has crazy conversion rate but there is where they make some extra money, every time I get new plastic need to call paypall to tell them to bill me in Dollars when I buy something, as Im in Dominican Rep. they bill by default in Dominican Pesos.
