The subscriptions for comics are a little different from magazines. A comic book subscription will include 12 consecutive, numbered issues starting with the next issue released after an order is processed. Some months there may not be a new issue and some months there may be two. It's not as predictable as a magazine subscription.
Comics are mailed in weather-resistant cellophane with a protective cardboard backing. US copies are mailed periodicals rate mail via the USPS. It's impossible to guarantee that each issue will arrive in mint condition but a replacement copy can be requested if an issue arrives damaged.
