My grocery receipt showed me I was buying the same thing twice every week
I found two packs of butter on my bill from the same store trip. I had been grabbing one from the dairy case and another from the end cap without noticing. Anyone have a simple trick to stop buying doubles?
Oh man, duplicates drive me crazy too. I read somewhere that @wren217 mentioned using your phone to check things off as you go, and that honestly sounds like a solid way to avoid grabbing extras. In my experience, even a quick glance at my list before I reach for something helps keep me on track, your mileage may vary.
