My last couple of spoke orders have gone to http://www.wheelbuildingparts.comThey sell 14gauge Sapim "Leader" spokes for as little as $0.28 without nipples. Can't recall if they offer every length or just odds or evens. Other spokes (DT, butted,) are priced about the same as Treefort or Colorado Cyclist etc. The service is good, shipping costs are reasonable. For nipples I've been buying DT 12mm nipples from Treefort or Nashbar. Boxes of 100 nipples for about $.06/nipple plus shipping which I think is $1.50. Someone sells nipples by 500 (maybe Treefort and Wheelsmith nipples) at even a better price. Used to buy from Rose bikes in Germany but had some issues with poor packaging resulting in broken boxes and lost spokes and nipples. One time they made good, the next time they told me to #sand .
