I have been printing Ker-bloom! since the summer of 1996, every two months without fail. Check my Etsy shop for back issues and special sets.
There is no additional shipping cost for people in the US. A small amount is automatically added to international orders to defray the additional mailing cost for everyone outside the US.
Note: The photographs accompanying this listing show my tables at recent zine fairs. They are not, however, images of exactly what you'll get, since I haven't even made the zines you'll be receiving. To see more of what my zines look like, check out the rest of my Etsy shop.
