As the cosmic titles get better and better, the sales are only holding steady at this point. To help promote the books, a group of us cosmic fans have joined together to form the United Front.
For more info, check out: The United Front website!
One way to help is to work with your local comic shop on ways to get more customers to check out the titles. I've created a 10% coupon sheet that you can download, cut into individual coupons and give to the shop owner.
To make it a little easier on the shop owner, you can offer to reimburse him/her for any coupons used. Which isn't too much to do. For example, if 10 coupons are used, that would cost you only $3.
