Back to my dollar bread

Well, I figured out that making one loaf of bread using a simple recipe of only yeast, flour, salt and water would cost about $0.22 . . . IF I used the bulk yeast in the freezer that I bought a while back from Costco.  I already shared my dilemma about Costco foods, so I then calculated the bread if I were to pay for that 2 ¼ teaspoons of yeast as if I’d bought it in a packet at the regular store.  The cost of the bread went up to $0.95.  So it is a no-go on the fresh bread, at least for tonight, and I’m a little bummed about it.  I know it's only 95 cents, but I just feel so scared to go over budget or have nothing left on the last day, and it is still the beginning of the week.  I may go to my bag of flea-market freezer bread instead.  Not the same, though . . .
