I forgot that one. Just near the end of last year I discovered the same thing. Had an old roll of TP that I sat a new roll next to and the difference in size was startling.
And in the meantime, the prices slowly continue to creep up...
I have a Dollar General near me; they really aren’t a bargain, but just have lower prices for smaller packages. I rarely see people doing full shopping trips there (though they have everything - just not a wide variety); most people (including me) seem to use it just for individual items forgotten on “real” shopping trips at Wally World or a full supermarket.
