In case it is helpful to gauge current timing and any improvements, I ordered my Waterbox 190.5 at the end of June. I received a shipping notice about 4 weeks later, and the offered shipping dates were less than 7 days from the notice. I will see what I get on Wednesday of next week, but I was shocked at the speed and responsiveness when I followed up.
Because it probably matters, I ordered before a major holiday and at full price. If you see my other recent threads, Waterbox later honored the July 4 discount when I asked. However, I suspect that I got a shipping window that was before a holiday sale crush.
I am sorry for everyone else who has had shipping problems.
