As Bob suggested, I would check out Southern Polyurethanes. They have limited colors, but if you need primers and clears, they are hard to beat. Their products are top notch. You can check the prices online and call them to order, if they don't have a jobber in your area.
You need to consider how the stuff it packaged for shipping when ordering that stuff. It needs to be packaged properly to avoid spillage, and damage. I have a friend that works for UPS, and he was really impressed with how SPI packaged the stuff I got from them.
