Buy more, pay less per item — shown right on the product page.
Tiered pricing that changes what goes in the cart: one bottle, two at 10% off, three at 20% off. The tiers sit above Add to cart and the saving is applied by Shopify at checkout.

The 45-second demo
How it works
Install and turn it on
Install ZS Bundles, press Turn on in theme and save. The widget appears above Add to cart on product pages.
Pick Quantity breaks
Create bundle deal → Quantity breaks. Tiers come filled in (Single, Duo, Trio), so you only adjust them.
Set each tier
A percentage, a fixed amount off, or an exact price per tier — plus an optional badge such as “Most popular”.
Publish
Choose the products, publish, and the tiers show on those product pages. Shopify takes the saving off at checkout.
Everything the offer needs
Percentage, fixed amount or exact price for each tier
Badges, subtitles and a saving line that fills itself in
Free shipping on a tier (for example, 3 pairs of socks)
Prices in the shopper's currency through Shopify Markets
Widget text in the shopper's language
Colours and layout that follow your theme
Where it works best
Consumables and anything bought more than one at a time: supplements, skincare, coffee, tea, socks, pet food, candles, printing.

Questions merchants ask
Do shoppers need a discount code?
No. The discount runs as a Shopify Function, so it is applied automatically at Shopify's own checkout.
Can one product have several tiers?
Yes — as many as you like, each with its own percentage, amount off or exact price.
Does it work with my theme?
It installs as a theme app block and is tested on Dawn, Horizon and Debut. It works on any Online Store 2.0 theme.
Can the tier discount stack with other discounts?
You choose in Settings whether it combines with product, order and shipping discounts.
Is there a free plan?
The free plan includes every bundle type and up to 20 bundle orders a month, with one bundle live at a time — enough to build, test and launch before paying anything.
