Please forgive my ignorance! I want to download an app (Facetime) but I can't get the App Store with my current OS. Apparently I need at least 10.6. Way behind the times, I know. When I go to apple.com and click on "upgrade to Snow Leopard," I get the page to upgrade to Lion, which of course I can't do because I have to buy it at the App Store, which I can't get without Snow Leopard. How can I download an upgrade to Snow Leopard? Is there a way to skip straight to Lion? Thank you for your time and patience!
