A BRIGHT IDEA?

I think that I just had a good idea. Lately, we have been buying mass amounts of milk. I thought that the kids were feeding every cat in the neighborhood or watering the lawn with but it turns out that they are actually drinking it. It is really getting out of hand. I thought about buying a cow but I have vowed never to have any more pets....but would a cow be a pet....or like a contributing member of the family....oh well, that would be stupid. What would the neighbors think about a cow in the back yard? Okay, so the cow is out. I have a much better plan any way. I noticed that a gallon of vitamin D milk is the same price as 2%(we do the 2% already). So what if I bought a gallon of vitamin D milk, pour half into an empty jug, and then fill both jugs with water. Ta da!!! 2%. I think I'm on to something. It's like buy one get on free!!! I wonder if that would work with with anything else? Orange juice? Maybe toilet paper. Just unroll one, separate the two layers and...Ta Da!!! Two rolls!! Hmmmm?
