Instructions:Received this along with Dell's Mailshot
Call 0870 152 4608 & Quote the above code (FIRSTBUY-0277)
I've tried to enter the code via the Dell Business website, it comes up invalid so no quidco.
Don't know if it's account/area specific (I have never bought from Dell but get mailshots all the time)
This voucher CAN BE USED IN CONJUNCTION with other promotions according to the T&C's
