They give you an ETA right beside the method of shipping in the order process. Mine said ~Sept 30th so I'm going to trust that. It's AI...I haven't heard of anyone being screwed over by them and I can't see why they'd start now.
Give it time, they have a lot of customers and are known pretty much around the world (people at Arnies know them and a few places in the States have done reviews on AI grenades and Propane Adapters).
