Are there any sites out there using Ubercart without prices? Is that possible?

I need to build a website with a shopping-cart. However, it's a shopping cart with variable prices. The final price depends on additional factors that would be captured after placing the order by phone. (their business is traditionally handled by phone because it has so many variables). So instead of a price, and/or total price, it would need to show something like "TBD" or "Contact for Price".
