During the holidays [and Easter is approaching fast] people tend to overspend buying that last gift or two they suddenly think of whilst shopping. I've been reading it somewhere that arming yourself with cash and a list of what you need to shop can help you avoid this, since with a credit card you can always make accommodations for that extra 'little' purchase. Sounds to me like a good way to save a little. What do you guys think? Does it help to shop only in cash?
