Cortana can be your frugal online shopping assistant

Microsoft's Cortana could already help you with shopping thanks to image search and sales reminders. Now, it might help you get the most for your money too. In the latest Windows 10 Creators Update, Microsoft has rolled out a pilot feature in Microsoft Edge where Cortana can help you find the best price for a product you're interested in buying. Right now, this feature supports 14 retailers, which includes Amazon, Walmart and eBay, as long as they're within the US. So, let's say you're on a product page for a vacuum cleaner on Walmart.
