You can check the shopping websites which accept paypal for payments Look out for paypal acceptance and paypal logo then you shop and pay via paypal
Majority of the online shopping sites give you an option to pay using Paypal. Look for its logo and if it is listed, you can easily initiate a buy using the "buy" button! If you do not have funds in your paypal account... then you can pay from your attached credit card as well! Regards, RightMan
