This has to be one of my family's biggest pet peeves!!

I usually don't buy ice cream by the pint; I buy it by the half-gallon or 5-quart pail. I've been noticing the "half-gallon" (64 ounces) getting reduced too (Dean's, Country Fresh, Land O Lakes, etc.).

I've also noticed tubs of margarine/spread (Country Crock, Parkay, etc.) that used to be 3 pounds (48 ounces) and are often still being advertised as 3 pounds but are actually only 45 ounces.

There are so many more examples I could give, but I'm sure you all have your own examples.
