I am interested to buy the English dictionary. I would like to know information about the English-English dictionaries in your store. I would like to know about details of the book. Please tell the size, type (hardcover or paperback), weight. Including a discount if buying in bulk. Could you recommend the best-selling dictionary in your store and how much is it? I would like to know new dictionary or update versions in the market soon? If so, when does the book is coming? I look forward to hearing your early reply.
