The only shipping they do is extremely expensive express shipping internationally. They had some adapters that were previously OOS come available, but the Pocket system was OOS. I emailed them, asking them if I could buy the adapters, have them put them aside, and reserve the Pocket, and have them ship it all at once whenever the Pocket was in stock. I even offered to pay it all up front so they weren't put out. They basically (politely) told me to suck it up, and buy both, and pay ~ 100 AUD each time to ship them express, separately.
Niche audio companies (eg Schiit) do this infinitely better!
The size of the company also explains the support issues.
