This is a crazy price for a great printer - just look at the spec!
I have searched the Internet for a better price and have found it advertised for every price between about £50 and £110. The Apple store usual price is £60.
There is a £5 postage charge but that still makes it a great deal - if you buy 4 you dont have to pay the postage.
The Apple store claim this deal stops on 31st July.
