finding a better price on Royal purple oil

[Norm reynolds]

Does anyone know where to buy Royal purple oil at a discount
I have found this site to buy all my wix oil filters cheep
http://www.fleetfilter.com/
I have had it with mobile one had nothing but troubles with it and amsoil I really did not think it was that great plus it is a pain to buy for a year now I have been using Royal Purple oil and found it to really work out great The only problem is the price at least at pep boys yesterday paid 8 bucks a Quirt so I am now looking on line fro a better price
Has any one found a better price when I did buy my wix oil filters I bought a 2 cases witch will last me tow years I am looking to do the same with royal purple
