Bulk vs. Not

For a long time I was under the impression that most things are cheaper when you buy them in bulk, but that is not always the case.  In fact most of the time buying a smaller box or bag of something will come out cheaper than buying in bulk.  The way to figure out which would be cheaper with your coupon is by figuring out the price per ounce.  You might find that in this case bigger is not always better.
