Not too long ago the snack manufacturers realized that a 99cent price tag for under an ounce of their product was really pushing the marketing limits. I'm sure some of us were buying two bags to get a real taste of those snack chips.
And the "New Bigger Size" was reborn. I say reborn, because a few years ago, this new size was THE size of snack chips.
As the costs of product went up, the contents of the bag went down. The physical size of the bag remained pretty much the same.
So what you're paying for is actually the bag, not the product.
Here's a video that sums up my feelings pretty well.
