Understand how BTD works, what the numbers mean, why deals are surfaced, and what you get with a free account.
Last updated 2026-08-28
A site that tracks real price history for a curated set of professional-grade tools and surfaces the ones currently priced well below their own recent history.
BTD monitors a curated list of approved brands and tool types through scheduled discovery cycles, tracks their real price history over time, and flags products whose current price has dropped meaningfully below their own recent average.
BTD currently serves the US market, with additional regional markets planned.
No. Browsing BTD's deals needs no account at all. An account adds tools on top of that -- see the next question.
You don't need an account to browse BTD. A free account gives you tools that make BTD work for you -- Deal Alerts, Deal Finder, Top Tool Deals, and the Deal Feed. Instead of checking BTD manually, you can tell it what you're interested in and let it surface deals that match. Browsing is free. Creating an account is free.
No. Creating a BTD account is free -- there's no subscription and no credit card required.
Browsing deals and opening a Deal Analysis don't require an account -- those are free to everyone. Deal Finder, Deal Alerts, and the Deal Feed do require signing in, since they're personalized to the tool types, brands, and price criteria you choose. Sign-in is free, doesn't require a credit card, and uses a one-time code sent to your email rather than a password.
A Deal Alert notifies you when a product matching criteria you set (tool type, brand, price range, how far below its own average) becomes a qualified BTD deal. BTD checks for new deals on its scheduled discovery cycles, and can notify you as found or include it in a summary.
No. BTD is not a real-time price-monitoring service. Alerts notify you as matching deals are discovered during BTD's scheduled monitoring, with matching events potentially consolidated into a single notification.
It has to clear several real, checked criteria: the brand and tool type are ones BTD has approved for tracking; the price has real, sufficient history behind it (not just a single snapshot); the current price is at least a meaningful percentage below that history; and the listing is new rather than refurbished, renewed, or used.
BTD only tracks a curated set of approved brands and tool types, and requires real, sustained price history behind a claim before it counts -- not every discounted product meets that bar.
Two reasons: the price recovered and is no longer meaningfully below its own 90-day average, or BTD can no longer find or verify the listing (delisted, long-term out of stock, or no longer matching BTD's tracking criteria).
The position a deal holds when every BTD Deal is ordered by deal strength -- #1 is the strongest deal, #2 the next, and so on.
BTD Rank reflects deal strength based on real, verified price history -- how much lower the current price is than what BTD has actually tracked for that product over time. It's the resulting order once every deal is sorted by that evidence.
No. BTD Rank reflects deal strength against a product's own price history -- not a claim that one product is inherently better than another, and not an endorsement.
BTD tracks a curated set of approved brands within each tool category -- Power Tools, Welding, Jobsite & Workshop, Landscape & Cleaning, and Measuring & Diagnostics -- including brands such as Milwaukee, DeWalt, and Bosch. See the full category and tool-type breakdown on the Categories page.
The current price BTD is tracking for this product right now.
The average price BTD has tracked for this product over the last 90 days.
How far the current price sits below the product's own 90-day average, as a percentage. This is BTD's primary evidence that something is a real deal -- a real, tracked comparison against the product's own price history, evaluated independently rather than taken from a discount label.
The lowest price BTD has recorded during the available pricing history. This is the lowest price since BTD started tracking this specific product -- not a claim about its entire lifetime on Amazon, and not a claim about the lowest price anywhere on the internet.
So "this is a good price" is a real, checked comparison against how this product has actually been priced recently -- not a guess based on a single snapshot. BTD waits until there's enough real history (typically 90 days) before treating a price drop as meaningful, since a newly-listed product hasn't been tracked long enough yet for BTD to be confident its recent pricing reflects genuine, ongoing behavior rather than a temporary launch price.
No. BTD LOW reflects BTD's own tracked history for that specific product, not a live comparison against every retailer or every price ever charged anywhere.
No. BTD doesn't sell anything directly -- it links out to the retailer, where the purchase happens.
On the retailer's own site, such as Amazon, not on BigToolDeals.
BTD participates in the Amazon Associates Program and may earn a commission on purchases made after following a BTD link, at no additional cost to the customer.
No. BigToolDeals is an independent site. It participates in the Amazon Associates Program as an affiliate, which is a commercial relationship, not ownership, partnership, or official endorsement by Amazon.
No. Affiliate relationships play no role in which products are discovered, which deals qualify, how they're ranked, or how they're presented. Commission rates have no bearing on qualification.
