At the grocery store, I always make sure to register my loyalty card before checking out, because it saves me a few bucks on eggs and milk. It's just a quick tap of the number at the keypad, but I've forgotten to do it plenty of times and kicked myself later. That small step can make a difference over a month of shopping.
