They still work, just not on everything. Next time you get one go to the "Saved Promo Codes" page under your account. It will be listed there & you can click on the "eligible items" button to see what it can be used on.Thank you for the responses, but yeah I was talking about the $20 thank you promos. The last one I got didn't work, and my latest one didn't as well. A bummer. I remember getting the 20 codes on the boxes, then randomly emailed after orders. Guess it's just dead now.
