Just ordered a Nikon D90 from currys for a total of approx 680.64
Currys web price is 779 for the Nikon D90 SLR with 18-105mm VR LENS
However by using the "70SAVE" discount code this prints the price down to 709 which beats argos /amazon by around 30 UKP.
instead of going direct go via topcashback.co.uk where you'll need to register, search for currys, and then enter the site that way, for a further 4% discount via cashback.
End result is 681 UKP -- not bad for a high end amateur SLR with a good starting lens
Remember this doesn't include a memory card, any UV filter, bag/case, external flash etc so this becomes the beginning of a somewhat expensive hobby....
(or 680.64 with topcashback)
