Each of the below checkouts could be on different pages.
The add to cart will take you to a PayPal page with the cart, but the return to shopping on that page can redirect them back to the cntaware.org page they were originally on on. from there someone could add an up & atom and a membership to the cart and pay for both at the same time.
These all have a 3% card fee except the donate button at the bottom- I needed names and values as the ‘donate’ button isn’t compatible with the add to cart option.
The view cart button could be after each add to cart so if they change their mind they can still check out. There is no “check out” button.
