The standard workflow for sneaker resellers is slow: find a pair on a retail site, copy the name, open StockX in a new tab, search the shoe, click through to the size chart, check the bid, manually subtract fees. A Chrome extension can collapse that into a single page overlay.
What the Profits Extension Shows on Retail Pages
When you install the Profits Chrome extension and visit a supported sneaker retailer, it automatically pulls live StockX data for the product on that page and displays it in a compact popup. No tab switching, no manual searching.
- Buyer Mode: lowest StockX asking price per size, total cost including buyer premium + shipping + state tax
- Seller Mode: highest StockX bid per size, estimated net profit after transaction fee + payment processing + seller shipping
- Color coding: green/red indicators show how retail price compares to StockX ask
- Advanced View: 1-year price chart, per-size listing depth, last sale history, aggregate ask/bid counts
Buyer Mode: Knowing the Resale Value Before You Pay Retail
In Buyer Mode, the extension shows what the same shoe costs on StockX as a buyer — including the buyer premium, payment processing, and estimated state tax. If the StockX all-in price is higher than retail, you are looking at an under-retail deal with positive resale value. If StockX is cheaper, the retail price is above market.
Color coding is instant: green means the retail price is below StockX's all-in ask, so you're paying less than secondary market. Red means you'd pay more buying retail than going direct to StockX.
Seller Mode: Calculating Your Flip Profit in Context
Seller Mode flips the perspective: for each size available on the retail page, it shows the current highest StockX bid and your estimated net after all fees and shipping. This is the most useful view for resellers — you see your potential margin before you add to cart, organized by every size available on that page.
Advanced View: Deep Market Analysis Per Size
- 1-year sales price chart: see how the resale price has trended over 12 months
- Listing depth per size: how many asks are stacked at each price level
- Last sale prices: recent transaction history, not just current asks
- Aggregate ask and bid counts: gauge overall market liquidity
The listing depth view is particularly useful for resellers: a size with only 2 asks above your price is more likely to sell quickly than one with 30 asks. It tells you how competitive the market is for the specific size you are considering.
Manual SKU Lookup for Off-Site Research
Not every pair you research will be on a supported retailer page at the moment you want to check it. The Profits extension includes a manual SKU lookup: enter any sneaker product code and retrieve the full StockX market data view — all three modes — without leaving whatever page you are on.
Installing Profits
Profits is a free Chrome extension by Payback, available on the Chrome Web Store. Install it, navigate to a supported sneaker retailer page, and the popup activates automatically. No account required.
