All the time, but never on "large" purposes. Large purposes I would define by things over $100 or just "more" expensive than usual like a $50 flashlight. However, I have splurged on a bunch of $1-$90 items, that I already knew I wouldn't use by the time I left the store. Recently, I bought $5 "flashers" and $5 reflective tape for my bike. After walking 2 blocks from the store, I went "WTF, I don't even ride at night....". Well, I mounted the flashers which now flap/rattle at low speed and the reflective tape is sitting in it's package unopened; too lazy to return $5 items. Then there are the bargain bin games, which got my attention cause they're sub-$20, but I have to bite the bullet to finish them so I can toss them in a corner. So on and so on... those "small" items rack up.
