Inspired by a similar deal on the NEX-3 with dual lens I just bought the NEX-5 dual lens kit from Best Buy via quidco. £549 less £55 quidco less £82 VAT back less £150 when I sell the 16mm lens. Net price should be c£262 for a NEX-5 with 18mm lens or the whole set for £410.
At £262 this is cheaper than even the best Jessops Clearance deal seen. If voting cold please say why as I may cancel if I am wrong
UPDATE: Quidco tracks at £55 (ie inc VAT price)
