Yes, you can buy it in the grocery store. Almond breeze makes a really good one. You can buy them in the area you find the soy milk over by the milk. They even have chocolate that lots of people seem to like (not me). They have unsweetened vanilla (I like that kind). There is also an unsweetened original that I like a lot too.
My favorite shake is almond milk, a banana, Restore (the protein powder you can buy at the store here), and peanut butter.
I also like to just add almond milk, Restore and a splash of orange juice. It tastes like an orangesicle. Sometimes instead of orange juice I add some raspberry juice.
I used to also do almond milk, Restore and frozen berries.
The ideas are endless.
I know people who even add their morning coffee to their shake. I also read that someone puts greens like spinach in their shake.
