My personal kryptonite is those Reese's cups right at eye level. I started making a list too, but half the time I'm just writing "do not buy the peanut butter things" at the bottom in all caps. It works most trips, but man, sometimes after a long day that candy bar just jumps into my hand, I swear. Saving that much cash is a huge win though, makes the few slip-ups feel less bad. I'm basically in a cold war with the checkout lane now, lmao.
