I don't do South Beach, but this week at Big Lots in their food section they had South Beach Diet Meal Replacement bars there for 50 cents each. They were not expired, but the expiration dates were 1-4 months away on most.
I know in regular stores they are around $1.00 each...so if you have a Big Lots near you, maybe this will save you a little money if you use them.
