I've used Honey, Ebates, Rakuten, Giving Assistant, Active Junky, etc. They all work the same way. They get an affiliate commission from the company and pay you a portion of it. There can only be one referral paid out. If you click on Honey and later, before you complete your order, you click on the Rakuten extension, the last one you click on gets the referral. I thought this was pretty common knowledge. I'm really surprised the content creators didn't know this before promoting it. If they had put any effort into understand what they were promoting they would have known.
