Shopify App : Easy Upsell

"Easy Upsell" is a no-frills way to upsell products to your customers post-purchase. Through the app, choose a product that customers would want to buy after checkout; your customers will be prompted to add that product to their existing carts.

How it works

1. Within the app, use the Product Selector to select a valid variant of a product that you’d like to upsell during the checkout flow. In the Page Headline field, specify the title that the customer will see on the post-purchase page.
2. After selecting a variant, click on the Publish button and a toast should appear confirming the successful creation of a post purchase offer for the user for the checkout flow
3. Simulate a checkout by visiting your test store's Online Store and conducting a checkout.
4. After checkout, you will be prompted to add the product to your current order. The offer has a 5-minute expiration by default.
5. If you accept the offer, you will be taken to the order confirmation page, where the product will appear alongside the other products in your order. If you decline the offer, the upsold product will not appear on the order confirmation page
