Just a quick update - My publisher has kindly allowed me to sell Hal Spacejock ebooks and signed copies via my website.
The ebooks are 4.99 each (mobi, epub and txt format included) or 15.99 for all four. When your payment goes through the ebooks are automatically emailed to you as attachments.
The paperbacks are all signed copies.
