Conversational Spanish in 20 Lessons

This entire series is very good at reinforcing one's foreign language skills. I have three Cortina book (Russian, Spanish & German) and all do a great job of refreshing common, everyday, conversational language skills. The pace is easy and there are numerous tips/advice that explain why a certain word or phrase is used. Every book has a decent dictionary with vocabulary and grammar exercises to help everyone from beginner to intermediate level.

Dear Sir, I will be very short! I bought the book some time ago. I am a Spanish teacher. From all the books I have, the one that more fits the group that I am working with is this one.I had been looking a long time for books;I am giving lessons to people in the horeca f.i.who knows nothing about Spanish, in a short time the basics of the the spanish language. I am now asking you if it is possible for me to order 25 books. What are the costs and how long will it take to deliver the books.If possible just send me an e-mail with some more information about the possibilities, costs, ways to pay and so on.Sincerly , A.S.
