I really enjoyed Get Rich Slowly's recent post Make Some Noise to Save Some Money, it's about how to get extras or fees waived just by asking.

I saw a big example of this recently: my boyfriend has been shopping for a new bike and could not decide between two bikes at different price points. He was discussing this with the bike shop and guess what they did? Offered to give him the better model for the price of the lesser one. The savings was huge, several hundred dollars, and he walked away with a great bike at the price of a mid-range one. You never know unless you ask.
