Ways to communicate on storefront

‍Goal or tiered progress bar in the cart or side/slide cart: This is the most crucial placement. The bar visually fills up as the customer adds more items from the eligible collection. The messaging should be simple and encouraging: "You've added 2 items. Add 1 more to unlock your discount!"‍
Collection page banners: Use banners on collection pages that state the tiered deal clearly, such as "Buy any 3 items from this collection and get 20% off."‍
Cart drawer messaging: Use a message in the mini-cart that reminds the customer of the quantity discount and shows how many more items they need to add.‍
Product page pricing table: The most common and effective method is a clear, simple table right next to the product image on the PDP. The table should list the quantity tiers and the corresponding price or discount (e.g., "Buy 1: $30, Buy 2: $25 each, Buy 3+: $20 each").
