Editorial interest 79/100 Selection signal · not a rating of the site

A repricer for Amazon listings that have lost the Featured Offer, with a randomly selected set of listings left untouched for comparison.

Landing page captured for the 2026-09-24 issue.

For: Amazon sellers testing repricing
Worth noticing: The page reports both the sales comparison and its limitation: one seller, used books, and a low cost per item.

Field notes

The page says the held-back group is drawn once before the first price change and stays unchanged for the duration of the relationship. Repricing is limited to listings that lose the Featured Offer; a price floor uses the seller’s unit cost and Amazon’s fee estimates. If Amazon has no fee estimate for a listing, the page says that listing is not priced.
