BTW, once the case series are done they don't usually send out the same sequences again.
That only happens when they find hidden cases in the warehouse, as in things that just went unnoticed and didn't ship, or canceled orders. Which is exactly what happened when we find old series 2 packs now.
For example, for the past three weeks or so, I could go to as many Walmarts as possible in my area and see the exact same case sequences at each one... week after week.
