PayPal has acquired Honey Science Corporation, the company that created the Honey deal-finding Chrome extension for a whopping $4 billion with mostly cash. Sounds like PayPal should have looked for a coupon on this one. Honey works with over 30,000 online retailers and the extension will automatically find coupon codes for things you add to your cart and will apply them for you. Sometimes the codes don’t always work or are not accepted but its one of the easiest ways to save money. Honey can also track prices and notify you when it drops below a certain threshold.

PayPal has not stated how the tech behind Honey will be integrated into their products, but executives say they want to build Honey’s functionality into the PayPal and Venmo experiences. PayPal merchant partners will also be able to use the technology to offer more targeted promotions. Honey’s name and co-founders will stay the same.
