Value Sort for Amazon

Re-sort Amazon search results by a tunable blend of review quality and price.

Value Sort re-orders the Amazon search results already on the page by a score you control: a blend of review quality and price. A slider sets the weighting, from quality only to price only. Review quality is not the raw star average. A 4.9 from six reviews is mostly noise, so ratings with few reviews are pulled toward a typical rating, and well-reviewed products keep their own average. An advanced setting controls how sceptical it is. Price uses the per-unit price Amazon shows on each result ("$0.52/Count", "$0.30/Fl Oz") when most results on the page share a unit, so a large pack is compared fairly with a small one. Otherwise it uses the list price. The panel always says which it chose. Where a result has no per-unit price, one is estimated from the title and marked "est"; those estimates are worth a glance before trusting. Sponsored results and products below a review count you choose can be dimmed and moved down, as are results that can't be priced on the page's basis (pods on a search ranked by weight, for example). Nothing is removed, and switching sorting off restores Amazon's order. Limits: it ranks only the results loaded on the current page, not the whole search. Prices are the price shown on the result, not including coupons applied at checkout. Privacy: nothing is fetched or sent anywhere. The extension reads only the search page you have open. Your settings, and the last 200 searches' price basis, are stored in your browser and never leave it. Works on Amazon's English-language stores. Independent project.
