Finding genuinely good deals at Walmart just got a whole lot easier. The creator of camelcamelcamel , a popular free Amazon price tracker, has launched an identical tool for Walmart products called camelmart .

California-based programmer Daniel Green created camelcamelcamel in 2008 as "a code experiment" with Amazon's Product Advertising API , he told Mashable last fall. It took off among shoppers (and shopping reporters ) after he put it online, so he hired a team of friends to keep it running — now for nearly two decades.

Camelcamelcamel and its browser extension, The Camelizer , can produce historical price charts for millions of Amazon products, making it easy to see if deals are worth adding to cart — or whether they're even "deals" at all. Users can also set up price-drop alerts to receive an email when an item goes on sale.
