The $4 notebook my aunt in Omaha handed me turned into my grocery map
My aunt in Omaha handed me a cheap spiral notebook over the holidays and I almost tossed it in the donate pile. She uses one page per store and writes down the normal price of the 15 things she buys most, so she can spot a real sale from a fake one. I tried it for 6 weeks and caught a "2 for $7" on pasta that was actually worse than the usual $3.19 a box. Just tracking that one item saved me $11 a month without changing a single thing I cook. She also draws a little map of the store so she walks each aisle once and skips the endcaps. Curious if anyone keeps a price log like this, and how often you update the numbers when everything keeps creeping up.
