Not much but I just scored a sugino 26.6mm seatpost with flutes painted blue for 3 bucks. it needs some polishing but is perfect for the '86 Schwinn Tempo coming my way (I think it should be 26.6, it's a 25" frame columbus tenax which is the same as my '88 premis which takes a 26.6 and my 85 norco takes a 26.6, not sure if it was the era or the fact that thicker tubes were used on large frames for stiffness).
