Was looking for Redflagdeals.com and found out royal purple is on sale. 5w30 1qt is on sale for 6.89 and they also have other grades too.

Here is their website: www.oneautozone.com
They are located at 46 Redlea Ave. Scarborough, Ont M1V 4S3
Anyways, I think it is a pretty good deal for those of who change oil by themselves or just want to stock up.
