Spend $25 and receive a tin of citrusy green tea, spend $50 and get the green tea and an herbal. Spending $75 gets you the whole set.
It's a really nice promo and valid until May 9th.
Shipping is $3.75 by UPS flat rate unless you spend $50 then it's free. (By the way, if your address is considered "rural," an extra $2 will be added to the shipping cost).
