There is no way to predict whether or not an AE will be offered as a refurb. I'd just keep checking the refurb inventory daily.
The airport express was on sale a few days ago.
Thats because the AE hasn't been updated since 2008 (or was it 2009? Too lazy to google it). The refurb available is the newest model.Hm I am not sure if I'm doing it right, but it says that nothing is in stock at all, when in fact most items are. Also, lol, the one item I am looking for isn't even listed.... AE 2011.
in theory that site is cool.
