Catch retail price errors before they're corrected.

Those sites are crowdsourced. Humans post deals they spot. Endless is an anomaly-detection engine: we scan full retailer catalogs on a schedule, store every price, and automatically flag products that drop 30 to 90% between scans, get mispriced across stores, or hit clearance markdown stages most shoppers don't know exist. No waiting on a deal-poster.

The pipeline runs around the clock. For Home Depot, the stores you save are rescanned three times a day, and a continuous pass covers the full catalog at all 2,000+ stores every two to three days. Dick's and Back Market refresh every 2 hours, Academy every 3, Nordstrom Rack twice a day. Newegg, Best Buy, Walmart, Macy's, Costco, and Apple Refurbished refresh daily.

We pull directly from each retailer's product API or page payload, the same data their app shows. Inventory and prices update as fast as we scan (three times a day for your saved HD stores). A price is only as fresh as its last scan.

Anyone can browse live Home Depot clearance chain-wide, free and without an account: same data freshness as paid plans. A plan (starting at $9.99/mo) lets you watch specific stores and unlocks title search, price-drop email alerts, penny-pricing predictions, multi-store watch, and the non-HD retailer feeds (Nordstrom Rack, Best Buy, Macy's, and more).

Penny pricing is a Home Depot specialty. Their clearance system uses cents-ending codes on shelf tags to signal markdown depth, and items with a price ending in $.01 are pulled from inventory and ring up at $0.01 at the register, regardless of what the tag shows. Penny finds are real and legal. They’re not advertised, only visible in the HD app or by physically scanning the SKU in-store. Other retailers we track don’t use this exact mechanism, but their clearance cycles are tracked and surfaced the same way.

Yes. Penny pricing and clearance markdowns are part of HD's official inventory liquidation process. The price the register rings up is the price you pay. That's how their ZMA (Zero Movement Action) system handles dead inventory. Not every cashier knows the policy, but it's enforced at the corporate level.
