Workmate told me that Nashbar has 15% off drivetrain parts until Sunday, so I go to order a few of the Nashbar 9 speed by KMC chains, only to find they no longer appear on the website at all! They were there earlier this week. Anyone seen this happen before? I was going to order the chains plus some other stuff anyway, but the cheapest chain is now a Shimano at $25. If it's just while this 15% off sale is happening, it will be cheaper to wait until it's over and order normally.
