StaleMate: Poshmark Age Finder

Overview

Reveal how long items have been sitting on Poshmark.

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.
