PayPal made its largest acquisition yesterday.

The online payments company bought promo code-finder Honey for $4 billion, betting that the Chrome extension and mobile product will give PayPal a leg up in deal discovery. 💸

A brief history: LA-based Honey was founded in 2012 and has flown somewhat under the radar since its launch. But early adopters quickly “got” Honey’s value — it saved them money while shopping and made googling promo codes a thing of the past.

“I was buying a GoDaddy domain, Honey automatically plugged in a bunch of promo codes and tested them all out, and I saved 14 dollars on a $15 domain. I only paid $1.24!” - Izzy

“Product discovery, where the right consumer has access to the right solution at the right time, is essential. Honey has the solution that people want, now it has to make sure it reaches all the interested folk through channel partnerships.” - Manisha

Honey now has about 17 million monthly active users, who are mostly on the younger side. Similar to an affiliate marketing model, the company takes a commission from merchants when shoppers use Honey (or its rewards program Honey Gold) to make a purchase. The product has saved shoppers over $2 billion to date and generated $100 million in revenue last year. 🛍

PayPal’s plan: PayPal (which currently has 300 million users) will add Honey to its own product line, which includes millennial-minded payments app Venmo. While Honey currently works with around 30,000 merchants, PayPal works with about 24 million merchants, and will now be able to offer more targeted coupons to shoppers.

While investors have historically discounted Chrome extensions, maybe this deal will change things. Some other extensions worth checking out:
