You did! If the part has to be ordered, you will not be.

My guess is the suppliers have him on a cash basis because he doesn't pay on time. That means in-stock stuff (what little there is) ships relatively quickly. Anything that needs to be ordered is a much higher risk and a completely unknown timeline — other than it is going to be late, very late, because he will need to pay in advance before they ship.

There is no need to support someone who chooses to do business like that. Life is too short, and other are too many good sources available today.
