"Bakery items are marked up nearly 100 percent as you’re paying for convenience. For instance, $20 supermarket cake can be made from scratch or out of a box at home for just $5 (or less by purchasing sale items and using coupons for the boxed goods).
Bread can also be baked inexpensively at home. Since most people won't bake bread at home, look for buy-one-get-one-free deals and freeze one loaf or buy when bread is marked down. Savvy shoppers will ask store managers when bread gets marked down — usually nearing the expiration date or end of the day."
