Quantity breaks

A quantity break shows a few pack sizes. Shoppers pick one, and your theme's Add to Cart button adds that many.

1. Heading — "Bundle & save" by default. Change it (or hide it) in Design.
2. Tiers — each pack size is a tier. The selected one is highlighted.
3. Badge — "Most popular", "Best value" or your own words, to steer shoppers to the pack you want them to pick.
4. Savings label — "Save 15%" is worked out for you from the discount.
5. A picker for each item — shoppers choose the size and color of every item in the pack (item #1 Medium in black, item #2 Large in sand…).
6. Your theme's own Add to Cart button — shoppers use it as usual. Your cart drawer, product options and checkout keep working exactly as they do today.

Set one up

1. Deals → Create deal → Quantity breaks, and choose a starting point:
   • Buy more, save more — 1 / 2 (−10%) / 3 (−20%). The safe default.
   • Stock up — 1 / 2 (−15%) / 3 (−25%) / 5 (−35%). For consumables and refills.
   • Start from scratch — build your own.
2. In Offer, adjust the tiers. For each one choose the quantity and the discount. The Offer guide explains every option.
3. In Products, choose where the deal shows.
4. Pick a style in Design and click Publish.

Ways to price a tier

Discount	Example	Shoppers pay for 2 × $35
% off each	15%	$59.50
Amount off each	$5 off each	$60.00
Price per item	$30 each	$60.00
Total price	$55 for the pack	$55.00

Under every tier the editor shows exactly what shoppers will pay, so you never have to do the maths.

Optional extras for quantity breaks

A size and color picker for each item

On by default. When a shopper picks a pack of 2 or more, each item gets its own row to choose its options. It works with variant options (size, color…) and with choice modifiers (dropdowns, buttons, swatches). Turn it off under Offer → Shopper choices if every item in the pack should be the variant chosen on the product page.

Let shoppers pick different products

Under Offer → Shopper choices, turn on Let shoppers pick different products and choose the products to offer. Items #2 onwards get a Choose button, so a shopper can buy one tee and swap the second for a different design — the tier discount still applies, because quantities count across all of them together.

Bundle options

Click Add a bundle option under the tiers to add a special tier that sells a set instead of more of the same: "this tee + matching socks, 20% off". The product the shopper is viewing is always part of the set.

1. The bundle option sits alongside your normal tiers, with its own price and savings. Shoppers pick options for each product in the set.

See Bundle options for setup.

Mix & match

Under Offer → More options, Mix & match counts items across all of the deal's products together — so "3 items" can be any three of the products the deal covers, not three of the same one.

Good to know

• Quantity breaks are enforced as bulk pricing rules on each product. If a product already has its own bulk pricing rules in BigCommerce, the deal can't add its own — remove the old rules or exclude that product. See Troubleshooting.
• Limiting a quantity break to certain customer groups switches it to a BigCommerce promotion, which counts quantities across all of the deal's products together.
• You can have up to 8 tiers in one deal.
