Depends on what type of account the person has. Personal account: you need a paypal account to pay them Premier account: can accept payment via credit card or paypal Business account: can accept payment via credit card or paypal Though they may have chosen not to accept credit cards (if thats possible) to reduce chargeback fraud.
If the product you are trying to buy requires a paypal account, it means that the vendor will not accept credit cards.
