It takes surprisingly little to trigger this effect/behavior.  I did a bulk 
buy of some 1960's era miniature vacuum tubes (500 pcs) for around 50 cents 
each; the next time I looked, the price from all vendors who had them had 
jumped to around $3, and it's up to $6 now.  (Fortunately the vendor I 
purchased from originally extended approximately his original pricing to me 
again.)  I think I was - and still am - virtually the only volume buyer of 
these parts, but the price remains high.  I've also had the same experience 
with other vintage new-old-stock parts.
