I agree with Laminar Lou's point of view. If you can get a killer deal, go for it. If not, then hold onto your money. I'd definitely recommend against getting more than a few changes or about a year's worth of oil. Speaking for myself, I don't like tying up my money in a non-liquid (financially speaking) asset. I'd rather have it either invested or sitting in an interest-bearing account where I can earn interest. Of course, if you can get a killer deal on oil, it can be said that you're getting a return on your investment that way. Still, buying more than you really is silly and can definitely become an addiction, as some on this site have clearly demonstrated. I also want the freedom to pick whatever oil I want from time to time and not be tied down to the 326 quarts I have on hand.
That being said, I currently have one case of M1 5w-30 ($3.83/qt at Sam's Club) and 6 qts of PP ($2.38/qt at Advance). This is up from 0 qts onhand about a month ago, not counting various partial quarts I might have for yard equipment.
