How it works
From campaign rule to checkout.
Split a custom bundle into named groups such as “pick 2 snacks” and “pick 1 drink,” each with its own item count.
01
Start with a custom bundle and choose the full eligible assortment.
02
Create up to five non-overlapping sections and give each a minimum and optional maximum.
03
Publish only after every section resolves to real eligible items.

What you control
The options that actually ship.
These controls are grounded in the current campaign editor and publishing checks—not a future roadmap.
| Control | What it means |
|---|---|
| Products, variants, or collections in each section | You choose this in the campaign or its matching Theme Editor surface. |
| Per-section minimum and maximum item counts | You choose this in the campaign or its matching Theme Editor surface. |
| Section labels shoppers can understand | You choose this in the campaign or its matching Theme Editor surface. |
| Up to five sections per campaign | You choose this in the campaign or its matching Theme Editor surface. |
What keeps it honest
Storefront display and checkout authority stay separate.

Cinch blocks overlapping section membership, including overlap found after collections resolve.
