You lost the Buy Box. Your phone should know before your sales report does.
Short answer
When your offer stops being the featured offer, Amazon emits a notification. Notifcentral subscribes to it, filters for Buy Box disqualification, and pushes an alert to your phone within about a minute - showing the current Buy Box price next to yours, both including shipping, so you can decide whether to reprice.
How Notifcentral detects it
Data source
Amazon SP-API notification
How often
Within about a minute
Amazon emits a notification the moment your offer becomes ineligible to be the featured offer. Notifcentral filters those events down to Buy Box disqualification and delivers the alert as fast as the queue drains - typically under a minute end to end.
What the alert actually looks like
These are the real notification strings the app sends, not mockups. Values are illustrative; the wording is not.
ASIN B07T9ZXKMNP is no longer eligible for the Buy Box
The current Buy Box price is USD 24.99 as opposed to your price of USD 26.50. Both prices include shipping. Act fast to reclaim your spot!
What it costs to find out late
The Buy Box is where the sales happen.
When you lose it, your listing effectively disappears. Most shoppers never open the "Other Sellers on Amazon" panel, so the offer is still live and still earning nothing.
82% of sales flow through the buy boxEvery hour without it is revenue gone.
A $50/day product losing the Buy Box loses roughly $41/day in revenue. Across a catalogue, a loss discovered on Friday that started on Monday is a week of compounding damage.
$50/day product -> ~$41/day lost without buy boxYou can win it back - if you know you lost it.
Repricing, restocking and fixing seller performance all work. None of them fire if nobody tells you the Buy Box moved.
What to do when it fires
Compare the two prices in the alert
The alert carries the winning price and yours, both including shipping. If the gap is small, a modest reprice often recovers the Buy Box immediately.
Check whether it is price at all
Buy Box eligibility also depends on stock, fulfilment method, and seller performance metrics. If your price is competitive and you still lost it, look at account health next.
Confirm you are not out of stock
A stockout hands the Buy Box to whoever is left. Check available units before assuming a competitor undercut you.
Questions about buy box loss alerts
It tells you the winning price, not the winning seller. Amazon's notification carries the competing Buy Box price including shipping, which is what you need to make a repricing decision.
Yes. Buy Box alerts can be filtered by SKU in the app, so a large catalogue only pages you about the ASINs that actually matter to your margin.
Buy Box alerts fire on loss - the event that costs you money and needs a decision.
