Royal Purple do it yourself Coupons @ Pep Boys
 

From another site I frequent..

It's GOOD for 2 oil changes of ANY Royal Purple Oil and RP filter for $35. I didn't even know they made there own filter.

The coupon expires 2/29/2012. You can print off as many you want you and bring them in to use them until they're ALL out. They will hold a rain check on the filters, but not the oil
