How To Upgrade Snow Leopard to Lion (not Mountain Lion) I couldn't find Mac OS X Lion in the App Store. Can I go from Snow Leopard to Lion without migrating to Mountain Lion?

Many programs are now dropping support for Snow Leopard (newer XCode, newer fortran compilers, etc.), but I don't want Mountain Lion. Mountain Lion still lacks support for some software that I like (ex. Little Snitch).

What are my (legal) options?
Call Apple, 1-800-My-Apple and order Lion over the phone. 

This is the only way to get it now. Apple will email you a code you use on the App store to download it.

BTW - Little Snitch is Mountain Lion compatible now.  I highly recommend upgrading to Mountain Lion.
