If a book is showing as out of stock, how long will it take to come back in?

Cheng & Tsui does its best to keep all of our books in stock and try to anticipate customer demand, but sometimes we may get a large order that we did not predict and we well out before a reprint or restocking order arrives. Most of the time a book that runs out is usually back within 1-2 weeks. But occasionally there may be times where it might take longer. Because we accept payment up front when you place your order, we don’t want to take payment for something that we are unable to ship right away. If something is showing as out of stock, please check back in a few days.
