Unless you have a specific need skip the extra cost of a service and just use the expedited option for renewal. Send your renewal application (you can fill it out online then print it) old passport, and passport sized photo via overnight express, pay the extra $60 for expedited processing and the $15 to have it overnight express mailed back to you. I did that in January for my first passport and it took seven from applying to delivery. Current processing time for expedited applications is within 3 weeks.
