Actually, shrinking the package while keeping the price the same is not a new concept. Been going on for years, long before Obama came along. Consumer Reports often has articles about this.
One example: Cat litter. Used to buy the 16 pound size of scoopable litter. Then it shrank to 14 pounds. Now, it’s 13.5 pounds.
Of course, there are some companies which shrink the contents AND raise the price.
Now that's brazen!
Same as dog food use to be 50lb bags then 44lb bags now they are 40lb bags.
