BitBuffet offers an easy way use PayPal's integrated shopping cart. The only difference between the single "Buy Now" buttons for purchasing a single product and the "Add-To-Cart" buttons for purchasing multiple items is that "Buy Now" buttons are created and copied from your product page in BitBuffet while "Add-To-Cart" buttons are created on PayPal's Merchant Services page.
For convenience, we include a link to the correct PayPal page for creating "Add-To-Cart" buttons directly above the corresponding "Buy Now" button on your product page in BitBuffet.

Please note the button ID circled in red, and click the Create Add-to-Cart Button to be redirected to PayPal. Be sure you know how much your item is selling for as well!

While you should notice that the item ID and price is already filled in for you, be sure to double check its accuracy. Any other field is completely optional. After you complete the button, PayPal will give you some HTML code. Use PayPal's code to place the button on your site, do not use BitBuffet's Buy Now button code.
