You’ve got a PFM app to help you manage your finances and a robo-adviser to help you with your investments. So why not let technology help you save money when it comes to shopping?

Online shopping solution provider Slice debuted its Slice Watch Chrome Extension this week. The new smart-shopping assistant allows users to track the prices of products as they browse online, alerting them that a given website supports Slice Watch. Shoppers click on the teal-colored Slice Watch button to get a pop-up that allows them to add the item to their watch list. If the price of the item drops, the shopper gets an e-mail notification. Slice Watch is currently supported by retailers such as Amazon, Macy’s, Anthropologie, Target, and Nordstrom, among others.

“Right in time for this year’s Labor Day sale season,” wrote Julia Handel at the Slice blog, “meet your smart shopping assistant that’ll save you time, money, and your sanity.”

Slice COO and co-founder Harpinder Singh demonstrated the Slice Platform API at FinovateSpring 2015 in San Jose.

Boasting the largest and most comprehensive collection of item-level purchase-data from more than two million online consumers, Slice enables financial institutions, e-commerce merchants, and others to build features and applications to improve customer engagement, personalization, and marketing efforts. Slice also provides consumers with a free app that makes it easy to track all online purchases, price drops, product recalls, as well as store receipts. The Slice app is available on both Android and iOS.

Founded in 2010 and headquartered in Palo Alto, California, Slice demonstrated its Platform API at FinovateSpring 2015. The company was acquired by Rakuten for an undisclosed sum in the summer of 2014. Read our Finovate Debut profile of Slice from last summer.
