Product Upsells
Summary: This section reviews how to add product upsells to your checkout page.
Important Notes:
1) The Product Upsell Headline field will not show unless you have a valid product ID in the Product Upsell ID field.
2) Make sure to separate product upsell ID's with a comma to include multiple products in the Product Upsell ID field.
3) If a product is already in the cart, it will not appear as an upsell even if you put the ID in the Product Upsell ID field.
