Mentioned previously in the forums is the 10% off Dell items with a quidco code - 7LZTMMW5L0M$WT
I phoned Dell and explained i would order if they combined this with the £70 off for first time buyers (http://www.hotukdeals.com/deal/53770/welcome-offer-for-70-off-a-dell-pur). I emailed them a picture of this leaflet (http://drop.io/dell_70_off_voucher).
Although they couldnt honour both discounts, they priced up at £730 including VAT and delivery.
This price will not be valid for long as the £40 off XPS and free delivery for the unit is due to expire soon.
RRP of the unit is - £938.99, saving £208.99!!
