During the whole month of July Cats and Crime is FREE at Smashwords when you use your Panzer discount coupon! That's Smashwords NOT Amazon.
I don't believe you have to have a Smashwords account. But, you do have an account, right? If not, the account is free too and easy to set up. And ... there are lots of free books at Smashwords.
Here's what you do. Click on the Smashwords Cats and Crime icon (not the Amazon icon!) on the right hand side of this page. Enter your account information at Smashwords. Click to buy in the format you want and use the Panzer discount coupon number SW100 when you check out. That's it. Cats and Crime is yours for free!
Tell your friends and they can get Cats and Crime free this month too.
