Zest Energy Tea 20 Sachet Packs $9.71 w/ S&S

Amazon currently has a 20% coupon for Zest Tea 20 sachet packs.
Total comes out to $9.71 with subscribe and save. Looks like you can only choose a quantity of 1.
For those who have never heard of Zest, it’s marketed as "energy tea" with each serving containing between 135 mg and 150 mg of caffeine. I personally have only tried the Blue Lady and it’s pretty good but I don’t think I’d ever pay $13 (regular price) for 20 tea bags.
Coupon applies to the following flavors:
- Apple Cinnamon Black Tea
- Blue Lady Black Tea
- Earl Grey Black Tea
- Pomegranate Mojito Green
- Spicy Masala Chai Black
- Superberry Samba
