Credit has to go to Farkison for posting the original Canon deal on this lens.
Nikon are usually marked up by at least £50 more than the Canon fit equivalent lens in Jessops, so this for the same price is a great price for a great lens.
Retails for around £210 upwards from what I have found for it, and have been looking for a while, almost plumped for the 18-200mm posted last week for £89.00, but upon going to Jessops to check they wanted £149.00 for that at the time anyway.
Seems to be collect in store only (at least for my area) but have found stock in at least three separate stores checking online then calling the store to make sure, so it is out there, just maybe try the "check stores further away" option if the postcode you enter doesn't prove successful.
Also Quidco too (if reserved online I guess) bringing the price down to £143.27 :)
