Seems like a very good price for a decent spec camera.
Up front cost is £179.97 but Canon offer £40 cashback on tophttp://www.canon.co.uk/springcashback/index.aspx
Best Amazon can do is £243 but you have to choose brown or pink (why do they make brown cameras? they always end up in the 'bargain bucket' section).
These were £310!
Some mixed reviews on Amazon so do have a read.
Don't forget 1.5% Quidco. Reserve and Collect
EDIT: changed price to reflect price drop
