Secretlab is doing a black Fri thing. The selection appears to be Omega and Titan chairs, no XLs. I'm not sure if it's all of the colours available but there's a great deal of choice there.
Some colours cost more. E.g. the Titan Rust at $664. I assume they are limited edition colours or something.
Shipping free to all states except WA and TAS. Looks like they're backed up though, so delivery windows are in December at the earliest for most of the ones I've looked at.
