Tiered quantity discounts on Shopify: buy more, save more

Tab Promo lets you add quantity tiers to a product discount, so the price per item drops as the shopper buys more, with up to 10 tiers in one rule. Each tier is a percentage or a fixed amount off every eligible item, and you choose whether quantities count per variant, across variants of the same product, or across everything in the offer. The discount is applied by Shopify at checkout and shows on each cart line.

Examples

Offers you can set up today.

Tee volume break

Buy 2 → 10% off, 3 → 15%, 4+ → 20% (counted per variant)

A shopper buying 3 of the same tee pays 15% less on all three.

Mix and match across a collection

Any items from the Socks collection: 3+ → 15% off, 6+ → 25% off (counted across all eligible items)

2 black pairs plus 1 grey pair reach the 3+ tier, so all three pairs get 15% off.

Per-item amount off

5+ units → $5 off each, 10+ units → $10 off each

10 units of one product get $10 off each unit, $100 off in total.

Wholesale tiers for B2B buyers

B2B company customers only: 5+ → $5 off each, 10+ → $10 off each

Company buyers see the tier price at checkout; regular shoppers pay the normal price.

Setup

How to set it up.

Start from the "Quantity tiered pricing" template. In Campaigns, click Create campaign and pick Quantity tiered pricing (or B2B wholesale tiers). It creates a draft with a sample two-tier ladder you can edit.
Set the tiers and how quantities are counted. In the rule, keep the discount mode on Quantity tiers. Add up to 10 tiers in ascending order, then choose: each variant separately, across variants of the same product, or across all eligible items.
Choose which products qualify. Limit the offer to all products, or include or exclude specific products, variants or collections.
Preview against a real order. Open Preview and enter a recent test order ID. You see which tier won and how much came off each line before anything goes live.
Publish. Open Publish, fix anything the check flags, then click Publish now. The offer goes live after Shopify confirms it.

Good to know

Where it stops.

Up to 10 tiers per rule, and each tier must start at a higher quantity than the last. All tiers in a rule are percentages or all are fixed amounts, not a mix.
The highest tier reached applies to every eligible item in the group. It does not blend prices (for example, first 4 at one price and the rest at another).
Free gift lines are not counted toward a tier when quantities are counted across all eligible items.
On product pages, a tier that pools several products is worked out from what is already in the cart. The price the shopper pays is decided at checkout.

FAQ

Common questions.

Does it change my product prices?

No. Your catalog prices stay the same. The tier discount is applied at checkout and appears as a discount on each cart line.

Can shoppers see the tiers before they add to cart?

Yes. With the Tab Promo app embed and blocks turned on in your theme, product pages can show the tier ladder and how many more items reach the next tier. Theme offers are included on every plan, including Free.

Does it slow down checkout?

The discount is calculated by Shopify's own discount system (Shopify Functions) during checkout, with no call out to Tab Promo's servers. Offer messages in your theme load separately and are built so they never block the cart or checkout.

Can tiered discounts combine with other discounts?

Yes, if you allow it. Each campaign has a Combinations setting that controls whether it can combine with other order, product or shipping discounts, using Shopify's normal combination rules. Inside one campaign, you also choose whether every matching rule applies or only the best one.

Can I use a discount code instead of an automatic discount?

Yes. A campaign can be an automatic discount or a code discount. The tier logic is the same either way.

Do I need Shopify Plus?

No. Tab Promo's plans don't require Shopify Plus. The only Plus-only feature is linking a Tab Promo product discount with a Shopify-native product discount on the same item.
