I do check the area asking my preference as to what to send, cancel order, etc...
I also will do as previously stated and leave instructions in a comment box.
Receiving a partial order, without my consent is not acceptable to me.
I don't care whether they email or call me, but please, one or the other!!!
I have also had them suggest another fabric, from the collection if my choice is unavailable. That was a nice gesture, also.
