Try StackLens: Discount Monitor

See how a campaign close to its usage limit is flagged, and why a partial scan cannot provide full-store reassurance.

Controlled sample data, not a customer success story. This demo never connects to a Shopify store, changes store data, or starts a subscription.

Each choice runs the app’s existing logic on the selected sample. These links also work without JavaScript.

What to do next in your store

Open the affected discount in Shopify and decide whether its dates, usage limit and combination settings match your campaign. StackLens is read-only. Rescan after your own changes; Pro adds broader findings, history, CSV and scheduling rather than checkout simulation.
