Ok I'm betting on when snow leopard is released those who have just bought leopard within a month or so before SL's release date will get to upgrade for a small price instead of having to shell out for a new OS. So my question is if I buy a brand new unopened Leopard box off ebay, as it is generally cheaper that Apple, Amazon etc, would I still be valid for the hypothetical offer I predict? How do these upgrade verifications work for purchases not directly through Apple? Of course I would need to know the SL release date to get my timing of purchase right. This is just to try and save a bit of money. Thanks for reading b.
