Thank you for all the responses. I guess I never noticed the tuna thing but it makes sense. I used to get a little more than two sandwiches out of a can and now it's just barely two. Thank god they don't want me to waste anymore

. The one I noticed last night was frozen chicken breast...now half the packages come in 40oz packages instead of 48oz but with the same price. Figures.
My wife uses Dove soap so I've bought that for years. They used to come in packs of 8 but recently changed to 6, all for the same price. On top of that those bars have gotten quite a bit smaller.
Didn't sugar used to come in a 5lb bag too? Those little bags of chips in the vending machine have gotten ridiculously small, in some cases, as small as 1 1/2 oz per bag.
Idk...not alot you can do. You can't even switch brands because it seems as soon as one company does it all the competitors follow. Only other alternative seems to make it yourself and, in most cases, that's just not practical (or I'm just far too lazy).
The thing I've noticed myself doing is buying more fruits and vegetables from farmers markets and a 1/4 cow and whole pig from a farmer friend. I'd like to say I did it to be healthier but, honestly, it was more like I'd rather pay someone local than send my money off to some big faceless company that'd screw me over any chance they'd get. Oh well, off my little soapbox. I'm going to have to look at my old recipes and the new product sizes and do a little greatest common denominator sizing...what a nerd.
