I have just received an email from Stormfront, they are an authorised premium reseller of Apple products. Currently they are offering £100 off a new Mac when you trade in your old machine regardless of the manufacturer, most people have an old PC/laptop knocking around that is never use. This does not apply to iOS devices, in the terms and conditions it says
"£100 offer applies to Mac Pro, MacBook Pro, MacBook Air, iMac. Offer does not include purchases of the Mac mini"
So although the offer is quite limited, it maybe worth visiting http://www.stormfront.co.uk to check if there is a store near you if you are thinking of getting a new laptop.
I am always interested in your thoughts so if you have any comments or feedback then please feel free to add any comments, or you can mail me here.
