first you have to sell something, then when payment is made it will be available in your paypal account, if you are a new seller the payment is held for sometime, i think up to 21 days..
Primarily PayPal (or some other form of electronic payment) or cash (pickup only).
Cheques and money orders can not be required by the seller when listing -- only if the buyer suggests it first and only if the seller is willing to use those slow methods.
