SellUp is the #1 Action upsell app for Shopify. This allows you to trigger an upsell on a products “Add to cart” button. The customer is then presented with up-to 3 Upsells based on your rules.
This makes SellUp one of the most powerful apps you can have for your Shopify store. It will also pay for itself, win win!
Kartify costs just $9.99 a month. With the increase in conversions and sales from motivating potential customers to purchase with messages, upsells and banners, it will more than likely pay for itself in no time.
A nice little booster. I found other upsell apps overkill. This was simple. Set the products and go. I would say 1 in 5 checkout with an upsell so this additional revenue has been very welcomed.
