There's a new Honest Company class action settlement for anybody who purchased qualifying products between 1/17/12 and 7/10/17. If you qualify, you may be able to receive $2.50 per item, up to 10 items total, without any proof of purchase. However, there is no max item limit if you have proof of purchase!
I'd like to point out that while I'm no lawyer 💼, I do know that by submitting one of these claims, you ARE using your signature under penalty of perjury. That means you don't want to lie! However, if you actually bought some of these items, feel free swearing to it and file a claim to get your rebate check!
