The way my PayPal has worked is that with my account, I get a specific OCR number which I use to make payments from my bank/post office - enter the OCR and pay into the Swedish account that PayPal has with one of the banks.
The OCR and name are read, and money is deposited into the PayPal account, after which I can use other people's emails that they have registered with PayPal to pay them **** (just enter their e-mail that they give me).
If I want hard cash, I need to tie my own bank account with the paypal account, and once that is done, I can tell paypal to pay in the sum on the paypal account to the bank account (naturally they have a whole set of laws and regulations to **** you up the ass on that one and keep the money to themselves, so the safest thing if you want money, is to tie a credit card to your paypal account and get your money that way)
Premium Accts are as far as I know - if you tie the credit card. The perks are listed on their site, usually the limit for sending and recieving money widening. My limit without the CC is 570 dollars or some **** like that, and it decreases or increases as time passes (never really paid that much attention to it anyway, most I ever paid was 20 bucks on intervals).
Hope it......helps.
