Can I add upsell products to my booster, and how many can I show? (Essential Free Shipping Upsell app)

Some upsell options depend on your plan. Check the plan details in the app before you set them up. You can choose one of two modes:

• Frequently bought: the app shows Shopify's product recommendations for the product being viewed. On cart pages, it uses the first product in the cart.
• Specific products: you pick the products to show. Products that are already in the cart are not shown again.

When several products are shown, they appear in a carousel. How many are visible at once depends on the page and the screen size. Exclusions filter recommended products, but they are not applied to products you pick manually. Check your manual selection yourself so that it does not include products you want to keep out.
