Right now PBK is selling tires with tubes for the same price as tires by themselves. Not as good a deal as they sometimes run, but still pretty cheap compared to the prices at the LBS. I'm waiting for them to get down below $35 so I can stock back up. My current set has almost 5K miles and while I haven't had a flat in all that time, they're starting to flatten down and get hairline cracks in the rubber. Hopefully when the riding season winds down, they'll go back on super sale.
