Wherever possible, I encourage you to support your local independent retailer when buying my work. If your retailer doesn't have the title you want in stock, give them the relevant order code and ask them to obtain a copy for you. Order codes can be found on each title's respective page.
(Ordering a title this way means you may have to wait a week for it to arrive, but you're helping keep your local store in business. It also increases the likelihood that the store will order more copies for their perennial shelf stock. Which may make no material difference to you, but it makes my accountant very happy.)
All of my comics and graphic novels are available through comic stores (some may also stock my prose novels). To find the store nearest to you, you can:
When ordering from a comic shop, you can give them the Diamond order code (e.g. STAR123456 or JUL123456) or the ISBN (e.g. 1-2345678-9-0).
Book stores stock prose novels and graphic novels, but not single issues of comics.
When ordering from a book store, you must give them the ISBN (e.g. 1-2345678-9-0) as they do not use Diamond order codes.
As stated above, I always encourage you to support your local store; however, if this is not possible then you can also order my work online.
Or you can buy my work from Amazon, e.g.
Videogames can of course be bought from major chains and online stores throughout the world. It would be superfluous to attempt to list them all here.
