Online shoppers often overpay for products simply because they buy from the first store they find. Comparing prices across multiple sellers manually is tedious and unreliable. Most existing coupon or deal tools only surface discount codes for the store you are already on rather than showing you the same product or a genuine alternative at a lower price from a completely different seller. There was no lightweight, in-browser solution that could intelligently analyze what you are looking at and surface real cheaper alternatives across stores in real time.
