Order copies now if you want to pay a fixed price of $10/copy including shipping

I am moving my main depot of books from Oman (home of the $5.25 per kg. worldwide printed matter airmail postal rate) to Canada in early December. As such, only until the end of November will I be able to send class sets of books anywhere in the world for the affordable price of $10 per copy, including postage. Thus, if you are thinking of ordering books for next year or for revision purposes this year, I ask you to please get your orders in as soon as possible.
