How to change reservations due to lower National base rate?

Plugged in my travel dates into the National Car website today and got a lower daily base rate! :p Yippie! But how do I change my existing reservation? When I accessed my existing reservation I couldn't lower the rate.

Is the only way to make another reservation and cancel the old one? How to cancel? Call it in? There doesn't seem to be a way to cancel on the website.

Never mind! I figured it out myself. Made another online reservation then cancelled the first one online using the menu at the bottom left hand corner of the screen.

That extra $3.50 will go towards gas, I guess! :D
