There’s something about prices ending in .99 that makes them feel noticeably lower, even when the difference is tiny. The mind seems to lock onto the first digit, so $999 gets processed as “nine hundred something,” while $1000 jumps into a different mental category. Retailers use this effect constantly, and it still works even when people know the trick. Curious how much of this comes from habit, perception, or the way the brain reads numbers.
