Along the same line of thinking, of note in SAMS CLUB, I regularly buy about 10 items 6 - 8 times a year.
I expect on any given trip to the store that I won't find one of the items because it happens 3 or 4 times a year.
The last time was Cascade powder dish detergent. So even an ordinary consumer staple was not available on the day I went to the store in November.
Let me add this as well. You know I am Heineken loyal and altho it does not happen often(maybe twice a year) sometimes Costco doesn't have Heineken out for sale. That beer is always on a pallet. But once in awhile it's gone. Maybe that was the case with Jefferson's. I'll keep a check on it.
