Cheaper than XYZ is a chrome extension that saves you money by automatically finding if the Amazon product you are viewing is being sold cheaper with another retailer. Our algorithms search live to see if your product is cheaper elsewhere. It works by searching multiple retailers online for whatever product you are viewing on Amazon. As this is a beta product it is currently being rolled out in the UK and US. We are extending out search capabilities daily to ensure we are able to search for the best price from over 420 million products listed on Amazon.
