We are a small volume, high product mix shop and buy quite a lot of 
our parts in dip tubes.  We usually buy from a distributor and they 
usually use rubber stops at either end.  (No pins in the middle, 
regardless of how full the tube is!)  We rarely have a problem 
with damage arrising from an unfull dip tube (bent pins, etc.), IF 
the tube is the correct size & geometry for the part.  They also 
occasionally insert plastic spacers (that slide out easily)  in the tube
if it's to be shipped partially full.  Tell your buyer to shop 
around!
