Creating Shopping Cart Buttons

When you use PayPal’s free Shopping Cart, your customers can purchase multiple items with

a single payment, browse your entire selection, and view a consolidated list of all their items

before purchasing. The PayPal Shopping Cart is a low-cost way for you to accept credit card

and bank account payments, and can be fully integrated with your website in a few easy steps.

Save time and money with PayPal’s hassle-free Shopping Cart:

z Easy to implement — no CGI scripting necessary

z No up-front costs — you’ll have the same low fee schedule as when you receive other

PayPal payments

z Sell with ease — PayPal maintains detailed transaction records on our website

The PayPal Shopping Cart also offers customizable buttons and secure payments to help you

improve your buyer experience, so happy customers become repeat customers.

Get the most out of your website today: start using the PayPal Shopping Cart!

How It Works

Bob, who is new to PayPal, is going to purchase several books from Alice’s website.

The following example depicts the flow that occurs when PayPal Account Optional is turned

off, and the user must create a PayPal account to complete the transaction. For more

information about the PayPal Account Optional setting, see Chapter 11, “Auto Return.”

What Your Customer Sees

Step 1: Bob goes to Alice’s website and clicks Add to Cart. When he has chosen all of the

books he wants, he clicks View Cart.
