Amazon price monitoring that tells you which ASIN just lost the Buy Box.
SkuEYE collects your Amazon US product pages on a fixed schedule, recording price, Buy Box offers, stock and data freshness. When something changes, you see the before-and-after price and the exact collection time before you decide whether to act.

Latest run failed to read; last valid snapshot kept and flagged stale.
Only a snapshot with a valid price, an ISO three-letter currency code and a clear availability status enters the price trend. This sample ASIN only demonstrates the link format; it is not a real monitoring result.
From a product link to a change you can act on.
No need to sit and refresh a tab. Add an Amazon US product page to your watchlist and SkuEYE collects it on schedule, keeping every run's result.
amazon.com/dp/B0BLXHWPLPThe platform and ASIN are recognized from the link; category pages, search pages and storefronts are not accepted into monitoring.
A trend only appears after at least two valid snapshots; missing points are never interpolated.
Before-and-after price, collection time and failure reason sit in one place, so you never mistake a stale price for the current one.
Amazon isn't an island.

Why the Amazon Buy Box deserves its own watch.
Buy Box ownership can flip with zero announcement: another seller on the same ASIN shaves a few cents off the price, the Buy Box moves to them, and your organic traffic drops right along with it. Refreshing the product page by hand rarely catches this fast enough — by the time you notice, orders and margin have usually already leaked away for a while. SkuEYE collects your Amazon US product detail pages on a fixed cadence, once every 12 hours, twice a day, and records the Buy Box price, other sellers' offers and stock status each time, so a change shows up as a before-and-after price with a collection timestamp instead of one isolated current value.
SkuEYE covers Amazon US product detail pages only — no category pages, no search results, no storefronts and no non-US marketplaces. A run's result only counts toward the price trend when the price is valid, the currency is an ISO three-letter code such as USD, and the availability status is unambiguous. A source timeout or a broken field mapping is recorded as a failed snapshot with its reason and is never disguised as a genuine price change. The trend chart itself only appears once at least two valid snapshots have accumulated, so you never draw a conclusion from a single data point.
Sellers who track Amazon competitors manually usually rely on browser bookmarks and spreadsheets, checking a handful of ASINs once or twice a week when time allows. That cadence misses same-day Buy Box swings entirely, and a manually copied price six days old looks identical to a fresh one unless someone remembers to note the timestamp. SkuEYE removes that guesswork: every snapshot carries its own collection time, every failed read is logged instead of silently skipped, and the dashboard makes the age of the data as visible as the price itself. That matters most in the exact moment a Buy Box flip is worth reacting to — before a slow week of lost orders turns into a slow month.

- Paste an Amazon product link. The system recognizes the platform and ASIN from a link shaped like
amazon.com/dp/<ASIN>; category pages, search pages and storefronts are rejected so out-of-scope pages never pollute your data. - Wait for two valid collection runs, roughly 24 hours. At one run every 12 hours, two valid snapshots take 12 hours in the best case and about 24 hours if a run in between fails and gets pushed to the next cycle — nothing is backfilled with stale data.
- Check the change and freshness on the dashboard. Before-and-after price, Buy Box ownership, collection time and failure reason all live in one place, so you can decide whether this change needs follow-up instead of piecing together screenshots yourself.
Amazon monitoring FAQ.
How often does SkuEYE check Amazon prices?
SkuEYE runs one collection pass every 12 hours, so twice a day. The dashboard shows the most recent collection time for every tracked ASIN.
Does SkuEYE track the Buy Box?
Yes, when the data source has it available SkuEYE records the Buy Box price and other sellers' offers. SkuEYE only reports what it observed; it does not determine Buy Box ownership and never changes your price.
Which Amazon marketplaces are supported?
SkuEYE supports Amazon US product detail pages. Category pages, search results, storefronts and non-US marketplaces are out of scope.
What happens when a collection run fails?
A failed run is recorded as a failed snapshot with its reason and is excluded from your coverage rate and price trend. After repeated failures the dashboard flags the product's data as stale.
How soon will I see a price trend?
A trend needs at least two valid snapshots. At one run every 12 hours that is 12 hours in the best case and about 24 hours if one run in between fails and gets pushed to the next cycle.
Can I also monitor TikTok Shop, Walmart and other platforms?
Yes. The same board lets you filter by platform: Amazon US, TikTok Shop US, Walmart US, Target US, Etsy US and Staples US all use a unified field format, making cross-channel comparison straightforward.
How much does SkuEYE cost? Is there a free plan?
Sign-up starts a free 7-day trial with full features: 3 products across all six marketplaces, manual refresh up to 20 times a day, and email plus Feishu alerts. After the trial, a free plan continues with 3 products and manual refresh twice a day. Pro is $49/month for 150 products with the same 20 daily manual refreshes and alerts. No credit card is required to start.
How does the 7-day refund work?
If you upgrade to Pro and are not satisfied within 7 days, contact us for a full refund, no questions asked. You can also cancel anytime from the dashboard; there is no lock-in.
What is the difference between manual refresh and the 12-hour scheduled capture?
SkuEYE automatically captures every tracked product on a fixed schedule, about every 12 hours, on every plan. Manual refresh lets you force an immediate re-check outside that schedule; how many manual refreshes you get per day depends on your plan.
