I was thinking about this the other day when I noticed my deodorant was 2.7fl oz instead of the usual 3. The stores are complicit. They know every time something shrinks because they have to print new tags. Even if it’s the old price, the unit price has changed, and I believe the barcode is different.

No warnings. No heads up. Just silent acceptance. Sure, if they posted a warning I wouldn’t buy that product but dammit I need deodorant!
