While the Shadow of the Templar novels and short stories will always be freely available and free on the web (for as long as I have any say in the matter), you can also buy physical copies via Lulu.
Right now the first two books are individually available as pocket-sized paperbacks; once all four novels and all the associated short stories have been written, a large omnibus edition will be released in both hardback and trade paperback editions.
Please be aware that in order to purchase the Shadow of the Templar books, you must register a Lulu account.
