buy cart changes code codes copy difference discount download edit editing email existing expiration item message number page price pricing product suggested variable variants

If I edit an existing product -- change my email message or download expiration for an item -- does the "Add to Cart" code change? Do I have to copy/paste into my page again?

I couldn't see any difference between the old code and the code that came up after editing.

No, the code does not change.

ADD TO CART code only changes if you change the "item number" or "variants" or "suggested price" (if you are using "variable pricing"). BUY NOW code changes if you change "item number" or enter discount codes for an item the first time.
