Halloween // Why are there no Halloweentown decorations?

I’m not talking about Nightmare Before Christmas, I mean Halloweentown. Whenever I go to Halloween stores, I always see the same movie franchises. Child’s Play, Beetlejuice, Hocus Pocus, Nightmare Before Christmas, Haunted Mansion, but never Halloweentown. And for once I want to go in and see Halloweentown merch. I want to see Cromwell Family signs and the Cromwell chant on T-shirts and other decor. I honestly don’t care much for the other movies. I just want Halloweentown. Does anyone know where I can find some?
