i got a new Capitec Debit card that allows online purchasing
i completed the Securecode setup part

now, when i try to set up my Paypal account, it says that my bank declined the request
contacted Paypal, they say its not their fault-have to contact Capitec & ask them to sort it out.

anyways, what i want to know is this:
im going to sell something to a person in the US

he will pay me via PayPal in US$
can i use those US$ now & buy something from Amazon.com?


thats the part i need explained

just say i got paid US$250
and i want to buy a Kindle Fire HD for US$120

how much will i be charged in bank charges & other transaction fees?
