What happens when more than one booster matches the same page? (Essential Free Shipping Upsell app)

The app can show more than one booster on a page. What appears depends on the booster type:

• Top or bottom bar: the app shows only one bar, even when several boosters match the page. The first eligible booster is the one shown.
• Product page: boosters are shown automatically. If a booster uses Custom position, the automatic product page boosters are not shown on that page, and the custom booster appears where you placed it.
• Cart page: the automatic cart booster is the first cart page booster that matches the customer's currency. To show a specific booster in the cart, use Custom position with that booster's ID.

Targeting decides which boosters are eligible. It does not rank them. Custom position is the way to choose a specific booster for a location.
