What food has decreased in size but increased in price over the last few years?

Oh man, I see this every single day while scanning items. It's honestly getting out of hand. Chocolate bars are the worst offenders right now. I remember when they used to be a decent size, but now they are basically thin slivers and the price tag has jumped up by like 30 or 40 cents. It feels like you're paying more just to get less than half of what you used to get a few years back.

Potato chips are another big one. The bags look exactly the same on the shelf, but when you actually open them, you're lucky if they're even half full. It's so frustrating seeing customers get annoyed at the register when they realize how much they are paying for mostly air. Everything from cereal boxes to those little snack packs seems to have "shrunk" while the numbers on the screen just keep going up.
