I'm posting this in case this applies to anyone who is waiting on parts from Vex.
Over the holidays, at the end of December, we received a shipment notice from Vex that said our long-awaited parts were on the way. The shipment notice even included a tracking number. So we waited and waited but the package never showed up. I was under the impression FedEx had lost it. But, thankfully, one of our people called Vex and that's when we found out the parts had not actually been shipped. We were told they would be shipped next week, instead.
Maybe it was just some glitch in their ordering/shipment fulfillment system, but in any case, if you're expecting something to show up soon, you might want to double check on the actual status.
