I have already emailed you, but obviously got the book wrong (COS340).
I am interested in 2 of your books, INF303 and COS321. Are you able to compare them to my post and see if the ISBN's match? If yes, then lets proceed to the check out counter! I have already ordered COS311 unfortunately. Could you possibly post them to me, I will pay (obviously). I am in Pmb. You are welcome to email me at email@example.com to finalise details.
