Same deal that has been posted a few times now. its back down to 419 again, but now a new offer means you can have the manfrotto 393 short photo tripod for just over a tenner which isn't bad, seeing as its normally 35quid for this tripod.
so in total its
£423.53 camera and kit lens + tripod (Before cashback)
£383.53 camera and kit lens + tripod (after cashback)
£419.99 camera and kit lens (Before cashback)
£379.99 camera and kit lens (after cashback)
The ten pound stretch for a decent tripod seems like good value but then again i don't know a thing about tripods so I'll let the more educated members confer and decide in the comments.
if you haven't heard of the canon cash-back heres a link:
