Quick Answer

A Walmart price tracker records how a listing's price and offer count move over time. Marter tracks that history and pairs it with the live profit math — fees, margin, sales estimates, seller depth — on the Walmart product page itself. For deep standalone charting, Marter works alongside Histomart, the Walmart-native equivalent of a Keepa chart. Marter is $24/month, single plan.

Most Walmart price trackers are built for deal hunters: they tell a shopper when something is cheap. Sellers need the opposite view — whether a price is stable enough to source against, how many competitors have piled onto the listing, and what the margin actually looks like after Walmart's fees. Price history without profit context is trivia.

Price history

See where the listing price has actually traded, not just today's number — so a temporary dip doesn't get mistaken for a trend.

Offer-count history

The most underrated seller signal. A listing whose offer count is climbing is a listing whose margin is about to compress.

Seller-level pricing

Who is on the listing and where they're priced, so you know whether you can realistically win the Buy Box.

Profit on top of history

Marter resolves price history into net margin after referral and fulfillment fees, using your cost of goods.

Stock visibility

A competitor priced below you with 4 units left is a very different problem than one with 400.

Price alerts

Get notified when price, offer count, or Buy Box ownership changes on listings you're tracking.

Price alone is the wrong signal

A Walmart listing's price is an output, not an input. It moves because sellers joined the listing, because stock ran thin, because Walmart itself started competing, or because a promotion ran. Two listings can show the identical price chart and be completely different sourcing bets — one with a single seller and steady demand, one with eleven sellers racing each other to the floor.

That's why Marter tracks offer count and seller pricing alongside price. The combination is what tells you whether today's margin survives your restock.

What about Keepa?

Keepa is the reference point most sellers arrive with, and it's excellent — for Amazon. Keepa does not track Walmart listings, and it isn't expanding to Walmart. So "Keepa for Walmart" is a workflow to rebuild, not a product to install: the historical charting layer comes from a Walmart-native tracker, and the profit, demand, and seller intelligence comes from Marter.

On price, the comparison is straightforward: Marter is $24/month with every feature on a single plan. Keepa is €29/month. Marter is the cheaper of the two, and it's the one that actually covers Walmart.

Where the history comes from

Walmart does not publish historical pricing. Every tracker builds its own dataset by observing listings over time, which means history depth is a function of how long a tool has been watching a product — not something Walmart hands over. Marter shows the history it has collected on the listing, and for the deepest standalone charts on Walmart items, Histomart has been tracking tens of millions of Walmart items continuously.

Frequently Asked Questions

How does Marter's price tracker work?

Install the Marter Chrome extension and open any Walmart product page. Marter loads price history and offer-count history inline, and once you enter your cost of goods it converts that history into net profit after Walmart's referral and fulfillment fees. The same data is available in the Marter mobile app via barcode scan.

Is Marter's price tracker a Chrome extension or an app?

Both, on one subscription. The Chrome extension runs on Walmart.com product pages for desktop sourcing; the mobile app covers in-store scanning. There is no separate plan or add-on for either.

Can I set alerts on price and offer-count changes?

Yes. Marter can notify you when a tracked listing's price moves, when the offer count changes, when a competing seller's stock drops, and when Buy Box ownership shifts — so you find out without re-opening the page.

Does Marter's tracker show competing sellers and their stock?

Yes. Marter lists the sellers on the listing, where each is priced, and their stock levels. A competitor priced below you with 4 units left is a very different problem from one with 400, and price-only trackers cannot tell the two apart.

How much does Marter's price tracking cost?

Marter is $24 per month on a single plan. Price history, offer history, profit math, sales estimations, alerts, the Chrome extension, and the mobile app are all included — there are no tiers.

Track the price. Then track the margin.

Marter shows Walmart price and offer history with the profit math attached. $24/month, one plan, everything included.
