ShelfRadar watches trading card and collectible restocks across the biggest retailers and shows you what just came back in stock, in one live feed, updated around the clock. No account. No sign-up. No subscription. Open the app and everything is there. LIVE RESTOCK RADAR See sealed product coming back in stock as it happens, with the retailer, the price we saw, and how long ago it landed. Filter the feed by category to cut it down to what you actually collect. FREE RESTOCK ALERTS Turn on the categories you care about and get a notification when something hot comes back in stock. Alerts are free and require no account. We keep a push token and your chosen categories, and nothing else. No email, no location, no profile. IN-STORE MAP See where items are actually hitting shelves. Search by ZIP code, city, or state, filter by store, and tap a pin to see what landed, which store, and when. Directions open in Apple Maps. The app never asks for your location. You type where you want to look. RELEASE CALENDAR Everything releasing now, plus a month by month calendar of what's coming. Know the street date before it arrives instead of finding out after it sells out. CARD INTEL Real market data, not guesswork. Worth Chasing: sealed product trading above MSRP, with the spread. Price Movers: what's climbing right now, and by how much. Grading Upside: raw versus PSA 10 prices, and the multiplier between them. RESTOCK FORECAST How often each product actually comes back, how long it's been since the last restock, and the cadence we've measured over the past two weeks. CATALOG SEARCH Search every product ShelfRadar tracks across all supported retailers. COVERAGE Thousands of tracked products across thousands of stores, monitored continuously, online and in store. WHAT WE TRACK Pokémon, One Piece, Magic: The Gathering, Disney Lorcana, Yu-Gi-Oh!, sports cards, and more. A NOTE ON LINKS When an item links out, it opens the retailer's own website, where the retailer handles the purchase. ShelfRadar never takes a payment and never handles your card. Some retailer links are affiliate links, which may earn us a commission from the retailer at no cost to you. ShelfRadar is not affiliated with, endorsed by, or sponsored by any retailer or card manufacturer. Product names and trademarks belong to their respective owners.
