Books

Hello everyone.

It could sound strange, but I have some money in my wallet (my grandma
insisted on tipping me for my results at school...). She gave me about $ 25.
I already had about $ 50, so I was wondering: is there a good and cheap (< $
50, possibly) Arabic grammar there out? I'd like it in English, but French
is welcome. German also accepted. If Chollie knows Italian works on the
subject, those are obviously accepted. And how much are those booklets
('Case', 'Gender', 'Tense', 'Aspect'...) by the Cambridge University Press?
I'd like to buy 'Gender'. Is it good enough?

Oh, and a technical info. If I don't have a credit card, can I order them at
Amazon.com?

Thanks in advance,

Luca
