Thought this was a cracking deal from an authorised reseller/dealer.
Price £235.05 minus 20% on currys website, applied at the end of the click through to pay making it £188.04 to pay. Then through the canon winter cash back promotion you get a further £25 back. Making it £163.04.http://www.canon.co.uk/wintercashback/
plus you can use topcashback or quidco for more off.
I know you can get it cheaper on the grey market, but from an authorised dealer its a great buy for this Canon STM telephoto lense
