It would appear that Sam's Club (possibly all of them but possibly only some) has canceled the Simply Right (in-house) brand of whey protein and has priced them to clear. This item is not on their website however I found it at the Deptford, NJ location. They had 33 left.
YMMV since you need to find a club that stocks it and one that has priced it to clear. I tried it and it wasn't bad tasting and mixed pretty good. Expiration date on my bag is June 2014.
I've uploaded a picture. I found the product in the 'Health and Beauty' section.
Amazon has it for about $40 shipped, but no reviews.
