Each month Sears rolls out a different set of coupons for all of their Auto Service Center services and products. They have Sears oil change coupons, air conditioner specials, discounts on tires, and a lot more.
You can find all of these advertised coupons on the Sears website. For as long as I can remember, they will always post at least one oil change coupon per month, usually at the beginning of each month.
They will also post some more Sears oil change discounts during different times of the year when oil changes are more common, like summer time. The summer of 2012 had a lot of different specials on oil changes, including the Road Trip Package Sale wich was discounted to just $99.97. This coupon got you an air filter, wheel alignment, conventional oil change, tire rotation, and multi-point inspection.
Sears also has plenty of tire discounts available that you can use when you bring your car in for an oil change. These tire specials are usually mail in rebates that get you a Visa gift card or some other monetary value for purchasing 2-4 tires.
The normal Sears oil change coupon that you might see is the $21.99 conventional oil change coupon or the $8 off of a synthetic oil change. Both of these discounts are great, considering the quality that you should expect to receive from you Sears location.
