The article spends a couple paragraphs complaining about Amazon not allowing sorting by unit price. This would be a very useful feature, I agree, but I don't think I've ever seen a online grocery or department store retailer which supports it. The brick and mortar retailers he praises don't let you _sort_ by unit price either, they just show it to you on the shelf (often because a regulation requires it), same as Amazon. Test search term: pretzels. Couldn't find a way to sort or filter by unit price at Target.com, Ralphs.com, Walmart.com, Vons.com, not even beloved Costco.com. If anyone does know a grocery or department store which lets you sort by unit price, I'd be interested to see it. https://www.target.com/s?searchTerm=pretzel https://www.target.com/s?searchTerm=pretzel https://www.ralphs.com/search?query=pretzels https://www.ralphs.com/search?query=pretzels https://www.walmart.com/search?q=pretzels https://www.walmart.com/search?q=pretzels https://www.vons.com/shop/search-results.html?q=pretzels https://www.vons.com/shop/search-results.html?q=pretzels https://www.costco.com/s?keyword=pretzels https://www.costco.com/s?keyword=pretzels
