Well, that sucks. I visit Sam's and hope it is just a Costco thing.
We make a fair amount of smoothies and buy fresh blueberries, strawberries and such when they're in season and freeze batches in quart bags. Then add enough liquid Acai/Pom juice so it will blend. I'm glad I have a VitaMix blender because it takes all the horsepower (2) that it can dish out to blend that stuff.
I test postitive for hepatitis, but don't have it. I guess I was exposed somewhere/sometime. Damn blood banks will not take my blood. I used to donate regularly. I wonder if the recipients of my old blood test positive too?
