Participating Panda Express restaurants offer a bottle of Sobe Lifewater for free via this printable coupon when you purchase a 2- or 3-entree plate. (You'll need to "like" their Facebook and fill out a short form to get the coupon.) That's the best freebie we've seen from Panda Express since June when we saw a free Orange Chicken with no purchase necessary. Click here to find a Panda Express near you. Deal ends August 16.
