Exactly. What was a pound is now 12 and in some cases 10 ounces. That has been happening since the mid 2000’s.
Some are quite devious. My bar of Dial soap has been on a diet for years now, even though the box is the same size. First, they whipped air into it, so it disappears faster. Then they changed its shape to make it “easier to grasp while bathing”. It’s only by accident that it also lost weight during its “shape change”. All of this is nothing more than a price increase.
Small tuna cans used to hold 7.5 oz. Then they reduced them to 6 oz and now they’re 5 oz. Actually, only 2.5 oz of meat and 2.5 oz of water. IOW, $4.61/lb meat. If you’re using an older recipe, you have to use 3 cans instead of 2.
