Grocery product manufacturers love to hide when they are giving you less for your money, but proclaim loudly when they are giving you more even if they really are providing nothing extra.
Example 1:
Clorox Clean-up spray bottles are adorned with a new claim that the product “cleans 40% more per spray*.”

It took a while to find where that asterisked claim was explained, but there it was in tiny print on the back of the bottle.
*MOUSE PRINT:

Well that explains everything… NOT. What in the world does that claim mean? Has the product been reformulated so it is 40% stronger than before and thus cleans 40% better?
We asked the company’s PR folks multiple times for an explanation, but they did not respond. Our guess is that the spray nozzle and feeder tube have been redesigned and now 40% more cleaner comes out with every spritz. That’s sort of like making the hole bigger on the toothpaste tube so you’ll use more.
Examples 2 and 3:
The most common type of “percent more” claim is designed to catch your eye and make you think you are getting a bonus — some extra amount free — because you picked up this particular promotional package.

When you look more closely at these two bottles, they are not giving you anything extra free. They are merely providing a mathematics lesson.
*MOUSE PRINT:

Both products are just larger size bottles than smaller ones. A 20-ounce bottle is (approx.) 40% more than a 14-ounce bottle, and a 36-ounce is 50% more than 24-ounces. Nothing more. Nothing free.
