Hi @cyberdave -
Sorry for any confusion! Persistent Shopping Cart is not what I mean…
If I have a website with 4 pages and I add Shopify Buy Buttons to page 4 and then add items to the cart - The cart is only on page 4 - If I go to page 1,2,3 there is no cart (with the items I added).
This is why, normally, I guess, you would add the cart code to the Custom Code Head section so it appears on all pages.
Thanks!
