I am writing to ask for information about English dictionaries available in Thailand at the Book Center. How much the prices and if discounts are available, especially if I am buying in bulk. And about the availability of English-English dictionaries, I would like to ask for a recommendation which dictionary they think is the best and how much it costs, and there be any new or updated version in the market soon? If so, When? And the book s hard backed or soft backed? And about sizes and weight? Please reply for my question by e-mail.
