Decided I wanted to have spaghetti for dinner last night. Grabbed two flavors of canned sauce, same brand but purchased two years apart (different flavors) and had them sitting side by side. Wasn't paying all that much attention until I went to stack something on top of them for a moment and when I did the smaller can of mushrooms was off kilter.

Hmmm says I why is that? Really took a look at the two cans and the one purchased two years ago was 26 ounces and the one purchased more recently was 24 ounces but the prices was the same for each purchase (.98 a can). So they are selling me less product for the same amount of $$. I've seen this in a variety of other products as well but that one caught me off guard. I obviously have not been paying as close attention to some of my purchases as others, so they got me on that one.

What other similar situations have you encountered?
