About StaleMate: Poshmark Age Finder

STOP GUESSING. START NEGOTIATING. Poshmark hides the date on listings, leaving you in the dark. Is that jacket a fresh arrival, or has it been sitting in a closet for 400 days? StaleMate reveals the truth. This simple, free extension stamps the exact "Days Listed" right on the image as you browse. WHY YOU NEED THIS: 👉 Spot "Stale" Inventory: Ideally, you want to find items that have been sitting for 60+ days. Sellers are tired of looking at them and are ready to accept low offers. 👉 Negotiate with Power: Don't ask "Is this available?" Send an offer knowing exactly how desperate the seller might be. 👉 Save Time: Stop clicking into listings just to investigate. See the age instantly while scrolling the feed. HOW IT WORKS: 1. Install StaleMate. 2. Browse Poshmark. 3. Look for the "Days Old" overlay on listing images. Built by a reseller, for resellers.
