B-Stock Buddy has shut down. Here is what it did, and what covers that job now.

It shut down. As of September 3, 2026, bstockbuddy.comserves a single notice: “B·Stock Buddy is no longer in operation. Accounts, subscriptions, and the Chrome extension have been retired, and signing in is no longer possible.” The notice gives an email address for questions and nothing else: no successor, no data export, no date for a return. The Chrome Web Store page for the extension no longer loads a listing.

We did not see a shutdown date published, so we cannot tell you when it happened, only that it had happened by the date above. The tool’s own guide was still live in an April 2026 archive snapshot, so the shutdown falls somewhere between April and September 2026. If you still have the extension installed, it has nothing to sign in to.

Going only by its own archived how-to guide (snapshot from April 21, 2026): it was a Chrome extension paired with a web dashboard, and it worked on bstock.com only. You opened a B-Stock search page or seller page, clicked “Analyze Auctions,” and every auction on that page loaded into the dashboard, sorted into Live and Closed. Each row showed the current bid, the retail value, the unit count, the time remaining, and a margin figure.

The margin came from an “expected revenue ratio” you set yourself (the guide says 50% of retail by default, adjustable per auction). Expanding an auction showed the manifest, and this is the part its guide called “the magic sauce”: each manifest line carried research links to eBay sold listings, Amazon, Google Shopping, and Facebook Marketplace, so you could check what an item actually sells for before you set that ratio. The guide does not describe alerts, other marketplaces, or anything that ran while your browser was closed.

BStalker (bstalker.com) is a liquidation-auction aggregator: one live feed across every B-Stock retailer storefront, Costco, Walmart, Target, Home Depot, and the rest, plus the other eight US liquidation marketplaces (Liquidation.com, DirectLiquidation, 888 Lots, Via Trading, BlueLots, GovDeals, Musick, and QuickBidz). It was already the “see everything at once” half of what Buddy’s dashboard did. Since September 2026 it also covers the manifest half:

• Per-item research links.Every lot with a seller manifest shows the seller’s own item list, and each line links out to eBay sold listings, Amazon, and Google Shopping for that exact item name. Plain links, no score attached.
• Closed comps.Ended lots from BStalker’s own archive, so you can see what similar lots actually closed at on the same marketplace.
• Cost per unit, computed the same way on every lot. Bid plus shipping where the platform quotes it, divided by units, so a Costco truckload and a Walmart returns pallet are directly comparable.
• Alerts. Saved searches email new matches as they appear across every covered platform and email you. You can scope one to a single seller, a category, and a cost-per-unit ceiling at once.

Two things Buddy did that BStalker does not: it linked to Facebook Marketplace, and it computed a margin from an expected-revenue percentage. BStalker has a resale what-if on each lot that uses a recovery percentage you type in yourself; it never suggests one, and it never scores a lot. That is a deliberate line, not a missing feature. There’s a live sample feed at bstalker.com/sample with no account needed: 65,873 lots are in the feed right now.

Roughly the same shape, in a different place. Instead of opening a B-Stock search page and clicking “Analyze Auctions,” you save a search in BStalker once (a seller, a category, a cost-per-unit ceiling, keywords, or any mix) and new matches come to you by email. Instead of expanding an auction in Buddy’s dashboard, you open the lot in BStalker’s feed: the seller’s item list is there, and each line has the eBay sold, Amazon, and Google Shopping links.

The bidding step is unchanged. BStalker’s job ends at the click-out: it shows you the numbers and links to the source. You bid on bstock.com under your own account, as you always did. If your entire sourcing life is on B-Stock and you never wanted alerts, the honest answer is that no tool we know of replaces Buddy’s in-page button, and B-Stock’s own site remains free to browse.
