Stock Checker & Restock
Selling an out-of-stock item gets you a defect. This prevents that.
Video tutorial coming soon
An eBay defect from selling an out-of-stock item hurts your account more than 10 successful sales help it. Stock Checker verifies Amazon stock levels before you list and provides inline monitoring buttons on your eBay Active Listings page. For each product, you can see the exact quantity available, the seller type (Amazon 1P, FBA, FBM), Prime eligibility, and current price. If stock runs low or goes out of stock, you know immediately — before a buyer orders and you cannot fulfil.
Pre-Listing Verification
Verify stock before listing — see exact quantity, seller type, and Prime status. Available in Product Hunter and one-click listing.
Seller Type Detection
Know who is selling: Amazon 1P (most reliable), FBA (good), FBM+Prime (acceptable), FBM (risky for delivery times).
Active Listings Monitor
Inline Stock Check buttons appear on your eBay Active Listings page. Check any product with one click.
Restock Button
When stock changes, click Restock to update the quantity on your eBay listing instantly.
Prime Status
See Prime eligibility at a glance. Prime products have faster, more reliable delivery — better for your buyer satisfaction.
Price Monitoring
Source prices change. If Amazon raises the price, your profit margin shrinks. Stock Check shows the current price so you can adjust.
How it works
In Product Hunter, click "Verify All Stock" to check every product before listing. Results show quantity, seller type, and Prime status.
Products with low stock (under 5) are flagged in red. Out-of-stock products are marked clearly.
On your eBay Active Listings page, UnicornDS adds inline buttons. Click "Stock Check" on any listing.
The extension opens the source product page in a background tab, checks stock, and shows the result — without leaving your eBay page.
If stock is low, click "Restock" to update the quantity. If out of stock, end the listing before a buyer orders.
