I'm in the exact same boat as you J so curious what people say. Personally the best prices I've seen and bought from locally are the 2 warehouse places in Bensenville. I got most of mine from New Fish, but at a buck apiece not that great a deal
AP had astraea snails and Tubos when I was there this weekend. I think he also had hermit crabs (not sure if blue or red. since I wasn't really like for them so didn't check)
He also had some kewl lettuce nudabranchs and I picked one up.
