My local Walmart has it. PBFit is on the baking aisle near the flour, and PB2 is on the aisle with the regular peanut butter. Both are surprisingly good, but PBFit is my favorite of the two.
I like mixing up some PBFit and spreading it on a low carb tortilla. Yum!
It makes a great treat, and is only 2 WW FreeStyle Points.
