I can’t understand the benefit of PayPal in the first place. I can write a check, wire money or even use a credit card. Why would I need another third party involved in my purchases & monetary decisions?
Because Paypal does not reveal your credit card info to the seller.
It lets people not worry about their CC number being stolen. It is useful if you are a small internet-based vendor. Buyers do not want to give you their CC number and you can’t really take checks or cash.
Paypal is a very secure way to purchase on a site like Ebay or Craigs List.
