I've been drinking almond milk as an expensive indulgence for a few years - I think it tastes much better than either soy or rice milk, but historically it cost about $5 for a half gallon. The only decent brand was Almond Breeze by Blue Diamond.
That seems to have changed with the introduction of almond milk made by Silk a couple weeks ago. Safeway had it at an "introductory price" of $2.79 (regular price $3.99) - an amazing bargain. I bought it - and received three coupons for Almond Breeze, one for a free half-gallon and two for $1.50 off a half-gallon!
So yesterday, I went to cash in my first coupon. (At this point, Almond Breeze had lowered their price to match the $2.79.) After claiming my free half-gallon, I got yet another coupon - this one for a free half-gallon of Silk almond milk, the one I bought in the first place!
So if you do the math, I've now gotten three half-gallons of the stuff for my initial $2.79 investment - less than a dollar a piece, not to mention the two coupons I still have that will bring the price down to $1.29 for subsequent purchases.
I can't promise that you'll get this deal too, because I don't fully understand Safeway's coupon-granting scheme, but it seems that right now competition is really working for the customers.
As an aside, the two brands are both good, although Silk definitely has a more pronounced "almond" flavor, which I kind of like. Both are better than Trader Joe's brand (formerly $1.99 for a shelf-stable quart, but now down to $1.69 - I assume as a consequence of the price war?), which is more chalky. Also, I only buy the Original flavor of all of these, because the Vanilla is cloyingly sweet.
