About OSI
Home Depot marks OSI OSI products through a predictable four-step cycle: 25% off → 50% → 75% → penny pricing ($0.01). Most OSI markdowns aren't advertised — they only show up on the shelf tag or in the Home Depot app.
Endless scans the full Home Depot catalog hourly across 1,990+ US stores. Sign up to filter OSI by markdown stage, store, and discount depth — and get email alerts the moment a new drop is detected.
