mustard

If I had not gone through chemo-induced menopause almost 7 years ago, I would think that I must be PMSing, cause I sure seem to be on a rant today.
We had take-out hamburgers last night from a locally owned dairy store. They raise their own cows for milk and also for the beef, so it is almost always good quality. Had one hamburger out of the "bag-o-burgers" deal leftover, so I just warmed it up for my lunch.
I got our mustard out of the fridge (French's) and noticed a new label on it. Looked closer, thinking it might have been a newer formula or something, but instead it says "40% More than our 14 oz ".
The bottle size is 20 oz, so I don't have a problem with that, but its just the idea that they are portraying the 40% more to be a special deal. I can see the required weight just fine at the bottom of the label, why do they feel the need to add a special "splash" label telling me the exact same thing?
Not sure why this bothers me, but today it does.
