I've had my nano for a few months now, however I wanted a case to protect it!
I've been looking around everywhere and all the cases I have seen have been at rip off prices many £12.99 + for a thin and flimsy case!
Anyway, I was looking in Sainsburys and by chance I came across a iSound Leather Case for the 3rd Nano! I tried it in store and it is a very good fit! - Good quality and for £4.99 a bargain!
I searched on the Internet and to buy exactly the same case online, you will be forking out £14.99!
It may be worth contacting your local store first just to see if they stock them as where I found them in store was a bit random!
