If anyone ever wondered why McMaster shipping is so high...
I received the last part of my order, Friday: the 4 foot long 3/4 OD 5/8 ID tube. It was packed in a 4 foot long box (4 x 4), which was in turn stuffed into a 5 foot long box (6 x 6), with stuffing paper.
Of course, I only need a few inches
I got casters for the case
