Hello thank you for all this information.
Is there a way to create a hyperlink that adds an item to the cart without taking them away from the current page? If a customer chooses a large variant on my site, a crate would needed to be added to cart. I have a box that appears that shows “hey a crate is required for this size Add to crate to cart ($50)”. I do not want to send my customer away from the current product page.
Thanks for all the help!
