Is it possible through shopify liquid, klavio, Omnisend or other app to have a pop up that has a 50% offer and a button that will add it to your existing cart?
I coded a button on omnisend
https://staywell-copper.myshopify.com/?add-to-cart=40353990705257
but it seems to create a new cart not add this discounted product to their cart.
I am using shogun as well for the landing page. When they click a product to buy I want this pop up to offer them one more at a discount.
any help or direction would be appreciated.
