Any length over 37" has been increasingly hard to find over the last year. Because of this, we are either sold out, or we have very little stock in the 37-40" and 41-43" range. When we are able to source it, the cost is very high. It fluctuates every time we find some, and it is getting harder and harder to find. We apologize for any inconvenience this may cause. Unfortunately this is out of our control.
