Data point:
I emailed Matuza requesting a Fire Red Pearl DMY box.
They emailed back the next day, "We don't have that sir."
I called them. "When are you going to get it ?" "We don't know."
"When was the last time you had it ?" [pause - recording] "About three and a half years ago."
"Hmmm, let me think on that, and I'll call you back."
I looked on their web site again, and saw the Black Cherry Pearl - sort of ok on a mostly black bike with red accent.
I called them back, and they said they had it, asked for my email, and emailed an invoice. I paid it.
Yesterday passed with no response.
This morning, I emailed them asking if they acknowledge orders.
I received an email back with the tracking number.

So I would say, on one data point, if they have it, they will send it right away.
If they don't have it, don't hold your breath.
