How sneaky. It is a shame you have to watch out for these kind of things.
Did you know that a lot of our favorite foods do this too. Yep, sometimes instead of going up on prices they change how much you get, same size box but if you look at the weight it is smaller. Sometimes the amount is not noticeable to us but a couples ounces per product saves them thousands of $$.
I personally think it is terrible to trick the consumer like that.
