Where is the buy button?

I was trying to purchase a new Canon S90 digital camera and found this great deal on the Dell Website.  I was all ready to purchase the camera but couldn’t for the life of me find the buy button.  Turns out you have to click on the Customize it button to purchase the camera even though there is absolutely nothing to customize.  I guess it’s a result of Dell building a shopping cart system for customizable computer systems and then using the same wording for other products.  It sure makes for a confusing buying experience.
