For those who check prices of a bigger shopping expedition, what are you checking against?
I have the unfortunate ability to recall the price of almost every item I get, and if it is on special or not. It's sometimes a curse as I can't let even a 50c error go. Countdown is pretty good and will give you the item (or the first of multiple items, with the rest getting refunded the difference) for free if it isn't a checkout operator error. New World quietly discontinued their 200% guarantee a few years ago and just seem to want to make getting a refund as hard as possible. I often wonder how many customers either don't catch the errors or don't care about it.
