Hello, I am from Argentina, where because of exhorbitant import taxes, mac prices are awfully high (i.e. basic mac mini is 1000 u$s, basic iMac 1600u$s) My question is this: When Apple releases a refreshed product (like the new iMac and refreshed mac mini) are you able (in the U.S.) to get the previous old models somewhere? and if so, are prices lower? how much? I am planning on going to the U.S. soon and probably do some mac shopping. Any advice is welcome. Thanks in advance. Pedro.
