Mixed Cart Limits
Keep incompatible products out of the same cart
Some products should not be purchased together. Mixed cart limits block incompatible combinations at checkout automatically.

Features
How it works

Select which products cannot be purchased together using tags, collections, or manual selection.
Checkout Validation
When customers try to checkout with incompatible items, they see a clear message explaining the restriction.

No theme modifications. Mixed cart limits work through Shopify checkout functions.
