Yeah, other than zoas and an occasional leather/toad stool you don't see many at the LFS. Diver's Den on Live Aquaria often has some interesting soft corals.
IDK guess just something different. I already have cabbage, shrooms, and zoas. Maybe something else that would go with LPS corals. Wheeping willow toadstool (is that what they are called?)
I have had good luck ordering from https://underwatergardeners.com/, they have a good selection and shipping is only $40.
