Looks like a nice package, but £25 for P&P? Are you going to deliver it by hand??
Consider a Buy It Now of £280 and you may well see it sells (but not to me, I don't like the DVD ones). Thing is that you're competing with the lower priced new ones, the extras are fairly incidental to most buyers and are always overpriced when new anyway. Definitely worth adding a Buy It Now price so that it qualifies for upload to Google Shopping (which is done automatically for listings that qualify, next upload will be on the 28th).
Also, it may take longer but you may well get more money by selling some of the extras such as the lens individually. No guarantee that they will sell, however, so it's a bit of a gamble.
Oh, and it has to be said that that is one of the worst pictures I've seen for an auction item! Ideally it should be 600x400 minimum, and show all of the accessories (consider using two or three to show them in more detail).
And another thing... this really should be in the Plug Your Auctions forum!
Good luck with your selling!
Here it is for anyone interested:
