Troubleshooting
How many items can one rule cover?
Up to 100,000 variants in a single self-updating rule — far past Shopify's native 100-item cap. Here's how it works and what the limits are.
Overlapping rules — only one discount applies
When multiple active rules target the same variant, what happens at checkout.
Rule matches no variants
When the live preview is empty — usually a conditions problem.
Rule isn't applying at checkout
Step-by-step diagnosis when a rule doesn't discount as expected.
Theme compatibility
The app works with any Shopify theme — including custom and headless.
