you can buy what you need a la carte. www.ogracing.com charges $7.50 for UPS Ground, and free shipping for orders over $100. www.jegs.com and www.summitracing.com charge $9 for UPS Ground regardless of order size. you can check www.redlineoil.com/dealers.asp for others, but I can tell you that the retailers (AutoZone, Pep Boys, Advance Auto Parts etc.) do not carry the gear/tranny oils.
