Two select Numi Teas for $7 [ends 6/14/16]

At Whole Foods brick and mortar stores, good until Sunday 6/14/16, many (but not all) of their Numi teas are on sale with essentially a two for one promotion. You pay $7 and get two boxes of Numi tea instead one. Many flavors are participating but not all. The Puerh and Turmeric variations did not have the promotional price on them. I forgot to price-check them at the register (and they are always busy). I do not know if you have to buy two of the same kind, or mix and match participating flavors. These are boxes of 16 to 18 tea bags each.
