My sister keeps buying 'cheap' food that costs her $80 a month extra, and I finally did the math for her
She grabbed 12 single-serve yogurt cups at $0.89 each at Kroger last Tuesday when the 32oz tub was $2.49, and when I broke it down per ounce she just stared at me, so does anyone else have a family member who swears they're budgeting but won't hear the unit price thing?
