I’ll admit it. Back in my carefree spendthrift days, I’d toss the cheese in the garbage when it turned moldy. I was oblivious to the fact that I might as well be throwing dollar bills away.

True, we could opt for buying just a few slices at a time from the deli counter, but that’s way too expensive. And unnecessary. I can save more than $2 a pound off the best price at the supermarket if I buy in bulk from a discount warehouse like Sam’s Club or Costco. And that presents the problem of storage.
