Wildman Rocketry Motor Question

Hello everyone, I am looking at buying some motors from Wildman Rocketry for my winter builds. However I have one question about buying from Wildman, since I have only bought motors from Apogee Rocketry normally I can buy a motor casing separately from the motor. However when I go on Wildman's website I can only buy motors, so my question is do the motor casings come with my purchase of the motor or do I have to buy the casing separately. Also I cannot for the life of me find where on Wildman's website to buy the motor casings so would I have to buy the casings somewhere else? If so does anyone have any favorites? I figured I would post on here before I emailed Wildman.

the motor casings are under the hardware tab

Oh thank you, for some reason in my mind I didn't think they would be there for some reason.
