WP Shop Cart allows you to accept payment from your customers using your PayPal account. If you are using PayPal Standard or Express, your customers can pay using a credit card or their PayPal account.
To enter your PayPal account details go to Settings > Payment Gateway Settings. There are two payment gateways available: PayPal and Manual Payment.
Click the check box for PayPal Standard or PayPal Express that you want to use to accept payments from customers and enter your account details. You can check them all if you want to use both, and on the checkout page, the customers will be able to choose what they want to use.
