As already said Louise, shop around and look at similar systems from other manufacturers, Panasonic and Sony in particular. A Nikon version has just gone on sale but it is more expensive and proper customer reviews will take a few weeks to kick in - and even as a confirmed Nikon freak, even I suspect it wont be any better than alternative cheaper options.
FWIW, This one you are looking at is the one I am considering as a hobby camera for when I am not working - small, flexible, lens options and I don't need a pack horse to carry it. I have looked at all of them, read all the reviews, and the only thing that is swaying me atm is the Fuji X10, but that's because it looks more retro and cute than this, but is also more expensive and doesn't has the lens flexibility, so in your case, I wouldn't recommend it.
As already said, forget all the 'free this and that' as most aren't, just find a good kit option at the best price from a 'known' retailer [you can always ask here about whether some of the online shops are reliable and legitimate] and if you get a few extra bits, all the better
