In addition to the previously mentioned price drops for Kindle and the standard paperbacks, there's a new offer running throughout September. While stocks last, signed paperbacks bought from this site will be discounted by a whopping 33%!
The coupon code for that offer is 09KABOOM18. You can shop for signed copies here.
The discount does not apply to the new Omnibus paperback, nor to the Whom Gods Shall Fear pre-order. It's available on the four individual paperbacks that are currently available.
In related news, it is now time to retire the mutating coupon code. This was the code found on the back of the business cards distributed through Armada Wars convention appearances.
