Used to grab the pre-cut bags for convenience, honestly. But you're totally right about the price difference, it's actually shocking. Started doing it myself last month and the savings are real.
Remember laughing at my own first attempt, ended up with bags that looked like they were cut by a toddler. Took me a few tries to get it right, but now I'm oddly proud of my crooked cuts. Still saving money though, so I'll call it a win.
When you say the savings are real, how much are we actually talking? I switched to cutting my own bags last year and it felt silly at first, but the real shock was seeing how much less I spent on foil and plastic wrap overall. What made the habit stick for you after getting used to the convenience? I almost gave up a few times because it felt like such a small thing.
