I finally compared unit prices at the grocery store and one box of cereal was 2 cents per ounce cheaper
I was standing in the cereal aisle at H-E-B in Austin last Tuesday with my phone calculator out, and I noticed the family size box listed the price per ounce in tiny print on the shelf tag. The big box came out to 11 cents an ounce while the regular box was 13 cents, so I saved about 90 cents buying the bigger one. I had no idea those shelf tags actually showed you that math, I always just grabbed whatever looked cheaper. Now I check them on everything, and last week I found pasta where the store brand was actually MORE per ounce than the name brand on sale. Does anybody know if those shelf tag prices per ounce are always right, or should I trust my own math more?
