Check with some LFS’. While it may take longer than trying to get one from the major online stores, you can get your name on a list or generally pay for one upfront so you know your guaranteed one. Again may take longer but you know you’ll get one. I was just lucky and was on the forum and someone posted in this thread that BRS had them and I managed to get one
If you have FB, saltwater aquarium has a secret group (Saltwater Insiders) where they post when they’ll have some in stock and when they’ll go online. Other than that, just continue to check this thread as some of us try to notify everybody when a retailer has some in stock
It's what I decided to do. Contacted a LFS that I've had pleasant dealings with in the past and asked to get on the list earlier this week. They said it would likely be a month or two which is fine as this isn't a need as much as a want. I only have 2 corals in the tank currently anyway lol! As a bonus, it supports a LFS.
