Popular Mechanics magazine is giving away $100 RockAuto.com gift certificates for each day in June. The gift certificates are good for brakes, exhaust, sensors, suspension, filters or any of the other auto parts RockAuto.com sells. To enter the Popular Mechanics sweepstakes, go to: RockAuto.com Gift Certificate -- Free Auto Parts - Popularmechanics.com
On the entry form, if you do not want the trial subscription then look for: "No purchase is necessary to enter. If you'd prefer enter the sweepstakes without starting a trial subscription to Popular Mechanics or if you are already a subscriber, click here." This is just above the box where "First Name" is entered.
