From now until April 1st, is the last chance to buy books from us directly at www.cm-dbcart.com without paying sales tax. As of April 1st, if you live in a sales tax state, your purchase will be assessed a sales tax. Unfortunately, this is outside of our control, and has to do with the lawsuit currently being fought by Amazon. So if you need an excuse to buy the rest of the Zhen Jiu Da Cheng, or the Jin Gui Fang Ge Kuo, now is a good time 😉
