When there are different offers with different discount amounts in one upsell popup, how it will work? Here is an example of one upsell popup having 3 offers with 3 discount amounts:
Because Shopify does not allow applying different discount amounts to different products in one checkout time, only one product is discounted in this case. The first product in the offer list will be prioritized to have the discount applied.
You can drag and drop to change the position of the offers.
