Stock will be pretty limited.
*more often than not when apple release new models they sell all brand new stock of the previous models through their refurb store as they never like to be seen as discounting, this cannot be guaranteed obviously and you may actually get a refurb. Also in the case of cancelled orders, this stock often makes its way into the refurb section and often with higher specs than advertised ie bigger hard drive, more ram etc etc*
Not bad deals for those not bothered about having the very latest model.
