I print off alot of materials and the cheapest/best I've found is overnightprints.com ... Tried vistaprint but the quality was subpar plus turnaround seemed a little slow. Just had some new business cards for a client printed off and got them here in less than 4 days and the quality was excellent(full color, bleed, heavy stock). As much as I print I would probably be better off working out a deal with a local print shop though. I would never use kinkos unless it was a last option, there prices are outrageous and quality/service sucks.
