Cow Loon,
Even though you didn't order it from the apple store, you don't need to. If your machine came with an OS X CD in a folder, than you are automatically able to get the 10.1 update. Even if you didn't buy a qualifying mac, you'll be able to get the CD. They aren't requiring proof of purchase...
Where there's a will there's a way... don't give up!
*pushes the soap box off to the side*
