I live in Brazil and have an iMac with Leopard 10.5.8. Is there anywhere I can download the $29 Snow Leopard update? The Apple store apparently will not ship to Brazil. I've checked the Brazilian web site where I bought the iMac and they aren't offering anything. They sell a little of everything so they are not really a computer store site anyway. I'd love to have this update especially if it can be downloaded.
