EXACTLY!The trend I am noticing is not only prices going up. But quietly they are reducing the amount you get in the packages as well.
I don't know about quietly though. I did my grocery shopping this weekend and I commented a number of times on how small packaging has gotten for several of the items I used to buy! It's disgusting!
First Make the "Regular size" 30% smaller.
Second : put the old bag in a box that is twice the size of the old box
Third: Advertise the Boxed product: 30% MORE THAN THE REGULAR PACKAGE.
Forth: Increase the price so the profit margin rises 10%
The result is that simply changing package size raises profits 10%
