Essential Upsell & Cross Sell

After our old upselling app stopped working, we needed a new solution and were looking for Built for Shopify upselling apps. We came across this one because it was free and had good reviews, and could not recommend it more. It has all the functionality you could want to set up a nice looking upselling widget quick and easy. The only things I've noticed is that when you press the add button it doesn't actually show the item is in the cart until you refresh and also the widget will go away if you add one of the upselling options and then go to a product with the same option.
