hi kim, if you have a whole foods, you can see it in the freezer section where you find the yummy ice cream and there are some acai drinks where there is the OJ and yogurt smoothies stuff.
the brand that i think makes great acai foods is Sambazon and you can check them out at
www.sambazon.com. I love their Acai ice cream (it's not really ice cream but that's what i call it) and their individual smoothie packs that come in 4s.
i believe there is also acai (the c is actually a french c - cidella i think is what it is called) in tablets form...but getting it in these foods is almost perfect.
