I've added a link at the top right of my blog to some of the online vendors who publish or stock my books and games. I'd rather people supported their local games shops and bookshops than feeding one of the big online stores (beginning with 'A'), but I also know that these days not everyone is lucky enough to have bricks & mortar stockists close by.
Every book of mine you buy new will probably buy me a couple of new 15mm miniatures. If you're after secondhand copies, it's worth dropping me a line first as I might be able to supply stock.
Thanks guv'nor, your donation is welcomed!
