and thats only one of the problems he mentions in the video

He says that when you click on an affiliate link, a cookie gets stored on your browser that lasts for 30 days, saying that the source should get the commission for your purchase. Honey has a popup in checkout, even when there are no codes, with a big “Got It” button to close the popup. Clicking the Got It button replaces the old cookie with a Honey cookie, giving the commission from your purchase to them instead of your source.
