Anyone looking to try this and hadn't realized it, it can easily be redeemed. There are two varieties readily available at WF.
Tip, you will need to submit as an "Any Grocery Store" purchase. I am assuming someone has done this, but don't recall any mention of it.
I bought the Ginger, Lemon, and Hibiscus a couple of times. Not a MM, but a buck and a half off $5.
I have tried most NA kombuchas on the market and had been looking to try a hard one. They are pretty good, decent alcohol content at 7%. I would recommend. Cheers/Salud.
