Today's Number, In Full
For every listing you name, AllyHub takes the price a shopper sees right now — beside the struck-through list price it's marked down from, and any clip-coupon sitting on top of that.
The price you decided on is last week's price. Give AllyHub the Amazon listings you care about and it re-checks them on your cadence.
Checking one Amazon listing takes ten seconds. Checking the twenty you actually care about, week after week, is the part nobody keeps up with — so the six below run from what a single check gives you to what a month of them builds.
For every listing you name, AllyHub takes the price a shopper sees right now — beside the struck-through list price it's marked down from, and any clip-coupon sitting on top of that.
The 12-pack and the single, the 128GB and the 256GB: each variation carries its own price, so the row you follow is the one you actually buy or sell.
Hand over a mixed list — your own ASINs, a rival's product URLs, the supplier listings you buy from — and they come back priced in one run, one row each.
Tell AllyHub what you'd buy at, or what you won't be undersold below, and every run marks the rows that crossed it — sorted before you open the file.
Ask it to compare this run against the last and it separates the listings that moved from the ones that didn't, which direction, and by how much.
Save the run as a Playbook and it repeats on the cadence you pick — nightly, Monday mornings, the fortnight before Prime Day — each result dated and written back where you keep your files.
From a handful of listings to a priced table you can re-run — Amazon price monitoring in three steps.
Paste ASINs or product URLs, or describe the items. Add the number you would act on, and the marketplace if it isn't amazon.com.
For every listing it captures the current price, list price, discount, coupon, seller, availability, and variation, then marks anything past the number you set.
Export the table, or keep it as a Playbook that repeats on your schedule; ask for the differences and each run reports against the one before.
Four things a chart pinned to a single product page can't do for you.
Amazon doesn't publish price history — the charts you've seen belong to whoever recorded them, and they stay behind that account. AllyHub can't hand you a decade on day one; it starts your record on run one, and that record sits wherever you filed it.

A price chart pinned to one product page answers one question about one item. When dozens of listings are in play you need to sort them and sit them next to your own costs — so AllyHub returns rows, exportable as CSV or JSON, not a picture.

Consumer trackers live inside a browser add-on; seller dashboards want an account first. AllyHub reads the public listing page — no Amazon API key, no Seller Central login, nothing to install — and a rival's listing reads exactly like your own.

The first run works out where each number sits on the page. Saved as a Playbook, the next one doesn't have to look for them again, so a check you repeat weekly gets cheaper as it goes — your AllyHub never starts from scratch again.

Sellers defending a margin, sourcers pricing a buy, shoppers waiting out a discount, and whoever reorders the same things every month.
A competitor moves on price and you learn it from a flat sales day rather than from the listing. Keep their ASINs beside yours on one watchlist, and the undercut shows up as a marked row on the next run — while there's still inventory left to defend.
The buy list you built in March was priced in March, and the spread you bought on may not survive until the pallet lands. Re-price the whole list before you commit, and the units that no longer clear your floor arrive already flagged.
A struck-through price is a claim about the past, not a record of it, and nothing on the page tells you whether the "was" figure went up in October. Start watching the item weeks before the sale, and the November number sits beside the one you recorded yourself.
Nobody re-checks the twenty supplies you reorder every month, so a few dollars of drift on each passes through the PO unnoticed. A repeating run prices the standing list and dates every check, which gives finance a line to point at when an invoice climbs.

The questions that come up before you hand over a list: what gets marked, where the record lives, and what runs for free.
An Amazon price tracker records what a product costs over time and reports the movement, so finding out doesn't depend on you opening the listing. Most of them follow one item and draw you a graph. AllyHub follows the set of products you name, reads the discount and coupon on the page as well as the price, and returns a dated table.
Yes — a one-off price check costs nothing. What the paid plans buy is scale and repetition: long watchlists, runs that repeat on a schedule, comparisons between those runs, and exports that land in your own systems.
Not from AllyHub. An Amazon product page shows the current price with no archive behind it, so AllyHub has no back-catalogue to hand you on day one — only every run you have made since, each stamped with its date. Keepa and camelcamelcamel can show you years because they have been recording for years; if the deep past is what you need, use one of them for that and AllyHub for the record you keep going forward.
There is no push notification, and nothing sits in the background staring at a listing on your behalf. The run itself is the answer: give it the number you'd act at, and every listing under it comes back marked at the top of the table. You decide how often that happens.
None of the three. AllyHub works from the public listing page, so there is no key to request, no add-on to install, and no seller login involved — which is also why it can price a competitor's product as easily as one of yours. Ask for the check in plain English; export the result when you want it elsewhere.
Every Amazon storefront: the US site, the European and Japanese domains, and the rest of the regional ones, all from one instruction and all returning the same columns. Mix them in a single watchlist if you sell or buy across borders — each row records the marketplace it came from.
Keepa and camelcamelcamel are archives you browse; a repricer is an engine that edits your Amazon prices for you. AllyHub is neither — it won't push a price back to Amazon, and it doesn't hold a database for you to visit. It reads the listings you name, returns them in a format you can use anywhere, and compounds with every task, so the same check in month three costs less than it does today.
