Volume Discounts (Buy More, Save More)

What volume discounts do

Volume discounts (also called “Buy more, save more”) give customers a bigger discount when they add more items. This helps customers quickly increase quantity and helps you raise average order value.

Before you start

Decide what the customer must buy more of (usually the same product or products in the same collection).
Choose your tier breaks (example: 2+, 3+, 5+ items).
Choose the discount type (percent off or fixed amount off).

Keep your tiers simple. Three tiers is usually enough (example: 2+, 3+, 5+). Too many tiers can confuse shoppers.

Set up a volume discount

In the app, go to Sales Boosters (AOV Features) → Volume Discounts (Buy More, Save More).

In Target (or Applies to), choose one option:

All products – the rule can apply store-wide.
Specific products – pick the exact products you want.
Specific collections – apply the rule to products inside selected collections.

If you choose Specific products or Specific collections, only those items will count toward the quantity tiers.

Add tiers to match the quantity a customer buys. For each tier, set:

Minimum quantity (example: 2 items)
Discount (example: 10% off)

Example tiers:

Buy 2+ → 5% off
Buy 3+ → 10% off
Buy 5+ → 15% off

Make sure each higher tier gives a better deal. If “Buy 5+” is not better than “Buy 3+”, customers may feel tricked.

Find Display style (or Layout) and choose how the offer shows in the cart. Common styles include:

Tier list – shows all tiers so customers can aim for the next one.
Progress / next tier message – highlights how many more items are needed to unlock the next discount.
Compact – a smaller view for busy carts.

Choose the style that makes it easiest for customers to understand what to do next (usually “add 1 more” or “add 2 more”).

If your goal is to increase quantity fast, use a style that clearly shows the next tier and how many items are left to unlock it.

Update the headline and tier labels so they are short and clear. Good examples:

“Buy more, save more”
“Add 1 more to save 10%”
“Best value: Buy 5+”

Keep your wording simple. Avoid long sentences inside the cart.

Save your settings and test on your storefront:

Add a targeted product to the cart
Increase quantity to reach each tier
Confirm the discount and messaging update at the right quantities

Targeting examples (choose the right option)

Target: Specific products

Use it when: You want a volume deal for one main product (like socks, candles, or protein bars).

Result: Only that product counts toward the tiers.

Target: Specific collections

Use it when: You want customers to mix items (like “Buy 3+ tees, save more”).

Result: Items in that collection count toward the tiers.

Target: All products

Use it when: You run a simple, store-wide volume promo.

Store-wide discounts can reduce profit if you include low-margin products. If needed, use product/collection targeting instead.

Best practices (to help customers add more)

Make the next step obvious: show “Add 1 more” or “Add 2 more” near the tiers.
Use clean tier breaks: 2, 3, and 5 are easy for customers to understand.
Call out the best tier: label the highest tier as “Best value” if your display style supports it.
Match your store’s style: keep colors and text consistent with your cart design so it looks trustworthy.

Volume discounts work best when customers can change quantity quickly in the cart. If your cart layout hides quantity controls, update your cart item settings so quantity changes are easy.

Common issues

Make sure you are testing with products that match your Target.
Confirm the cart quantity reaches the tier minimum (example: 3 items for “Buy 3+”).
Check if another automatic discount or app is conflicting with discounts.

Switch to a display style that shows the next tier clearly.
Shorten your text (example: “Buy 3+, save 10%”).
Reduce the number of tiers.
