Thats impossible man...I live in Canada, the land of high prices, and I can get a case of 12 litres of Bradd Penn Grade 1 in a case for fifteen bucks cheaper then if I was to buy the equivalent of regular off the shelf oil on SALE!
Get with an oil supplier nearby you, im sure you can score the stuff without the shipping and for a price just as good as off the shelf oil...plus, if I remember correctly your guys Autozone's should carry Valvoline VR-1 oil, as I remember guys posting coupons for it not too long ago
