These are visit-only checks. Closing this page stops them. These controls do not monitor merchants or prove live stock, purchase eligibility or a shipping batch. Review separate background-delivery settings.

Opting in stores rule IDs and bounded dated source baselines in this browser. No account or personal contact is needed. Source names, search text, coordinates and merchant URLs are not copied into alert storage.
Stopping removes this page's local delivery opt-in. Separate background subscriptions have their own stop control. To revoke the browser notification permission itself, use this site's browser permissions.
Nearby origin for saved distance filters
Choose your nearby starting point.
Optional. Enter a pilot ZIP or request device location. No automatic location lookup.
No location selected. The directory shows all matching reviewed stores.
Nearby requests go only to this site. Location is kept out of page URLs, sharing links, analytics and vendor links. Device coordinates are rounded and not saved. Distance does not establish purchase or cross-state eligibility.
Distance rules pause without an explicit current starting point. Their observation baselines stay in memory for this visit and reset when that origin changes. No state border is treated as a distance or eligibility boundary.
Changes from this check
No check has run. First successful checks establish a baseline without notifying.
At most 12 rules, 24 complete matching offers per rule, 500 retained identities and deduplication keys per rule, and 3 notices per check are processed. Narrow broad filter lists before checking. These are local resource bounds; no paid tier raises them. A source 7 UTC calendar days old cannot trigger. Failed, partial, hidden, unknown or incompatible observations do not become stock or price changes. New matching listings are not product launches; current-lot changes require an explicit reviewed exact match. Unknown or missing dates are not fresh batches.
