Hi Guys! I need to find app, to make extra offers popup after pushing "add to cart" button like on this site: https://cardsplug.com/collections/select-design/products/s20-one-to-watch Please, help me. Thank you!)
I think this is the kind of app you are looking for.
As you can see from there third feature with the picture below you can, Show the popup with upsell products to make more money After user hit Add To Cart button.
Does that work for you? Let me know :)
