The prices of the new Ipod Nano are pretty much going to be the same everywhere you go unless you work out a deal with Apple. If you find a really low price then they are more than likely fakes so beware!
Hmm, I can just help you out with your woes. I happen to know of a supplier who's able to supply at a lower price than USD 200. But yeah, there's a MOQ of 5-15 (depending on the model) to begin with. If you are keen, do drop me a mail.
