I placed an order with KWK on Saturday morning and it shipped Monday afternoon. I'm pretty sure Cactus and KWK still share the same facilities, though their order processing may be different.
Update for 10:30PM North American Central Time: the package just arrived in the nearest large city, about 2 hours from here. That usually means the package will arrive tomorrow. Yay! The original estimate was by Thursday Evening.
Anyway, RevRad, I hope your kava is on its way too. Maybe ping Cactus and ask if you don't hear from them after tomorrow.
Oddly enough it came today and I never got a shipping notification. Maybe it was in my spam folder and I missed it, or maybe their system has a temporary issue. Works for me though, decent shipping speed.
