sorry if advertising non-moz is not allowed!
but i have all six harry potter audio books (unabridged and read by stephen fry) for sale. they are one dvd mp3. also included is the chronicles of narnia.
good quality - i'm a fan myself!
here is a fuller description...
but the description does not include the chronicles of narnia even though it is on the disc. i think though that it is abridged (many many hours though!), can't be sure, never read it! i'm a potter fan and narnia is just a little extra!
if you're interested please pm/email me.
p&p is same as stated on ad link above ie FREE for uk, £3.50 europe, £5.50 elsewhere.
