Box sizes and discounts
Offer several bundle sizes, each with its own discount, so bigger boxes save more.
Box options let customers choose how big their bundle is — Box of 6, Box of 10, Box of 12 — with a different discount on each.
Turn box sizes on
Open your builder and go to the Products tab.
Find the Quantity as an option card.
Make sure Enable quantity as an option is ticked. It's on by default.
Untick it if you want a single fixed bundle size instead of a choice.

Two box sizes set up: 1 a Box of 10 at 3% off, 2 a Box of 12 at 5% off. The arrow points to Add Option, which adds the next one.
Add a box size
Click Add Option.
Title — what customers read, for example Box of 10. Required.
Quantity — how many items go in this box. Required, minimum 1.
Discount Type — No Discount, % Off, or Fixed Price.

Enter the value in the field that appears.
Click Save.
Each new box is pre-filled with a title of Box of N and a quantity that steps up in sixes — so you'll usually want to change both to your own numbers.
Fields
| Field | What it does |
|---|---|
| Title | The label on the box selector tab. Required. |
| Quantity | How many items the customer must pick. Shown prefixed with x. Required. |
| Discount Type | No Discount, % Off, or Fixed Price. |
| Discount (%) | Shown for % Off. Capped at 100. |
| Fixed Price | Shown for Fixed Price. The amount is in your store's currency. |
Use the trash icon on a box to remove it. You need at least one box. The first box you create is the one pre-selected for customers — there's no separate setting for it.
Check the currency on Fixed Price
The Fixed Price field currently shows an INR prefix regardless of your store's currency. The value you type is still in your own store currency — only the label is wrong. Ignore the prefix and enter your real price.
Fixed Price is the price of the whole box
Set Fixed Price to 40 on a Box of 10 and the customer pays $40 for all ten items, not $40 each. % Off works the other way — it's a percentage off the box's normal total.
A ladder that works
| Box | Quantity | Discount |
|---|---|---|
| Box of 4 | 4 | No discount |
| Box of 6 | 6 | 10% off |
| Box of 10 | 10 | 15% off |
Three sizes is plenty. Make the middle one the default and the largest one clearly the best value per item.
Show the saving on the tab
The box selector tabs can carry a discount badge. Turn it on under Design → Sidebar Widget → Discount Badge and use {{discount_percentage}} in the badge text.
