Priceline doesn't take one way air ticket?

[wjones]

I need a one way air ticket but looks like priceline only offer round-trip ticket (correct me if I'm wrong).

You can guys beat this price for this trip?
Depart: 2/4/01 or 2/5/01
From: BZN
To : SJC

Cheaptickets.com - $261.50
Lowestfare.com - $261.50
Expedia.com - $261.50
Travelocity.com - $261.50
Priceline.com - UNKNOWN

Why are they all the same price?????? Any other cheap ticket website?
