Print-On-Demand is wonderful new technology that allows us to publish books without having to invest capital in, and maintain, large inventories. Instead, books are printed as they are ordered and shipped directly to the customer. We also save by having others fill orders and ship for us. In the case of Amazon, the printer puts the book in an Amazon box and ships them directly from the plant. It is a bit more expensive way to publish each individual book, and we have to reformat each book in order to publish this way, but our savings outweigh the cost.
We still maintain a small inventory of books that we obtained from Timeless Texts, but as those books sell out, they will be moved to Print-On-Demand.
