I have dealt with other part time vendors and people who supplement their income working their crafts on these boards. I have had one instance when someone had a family issue that cropped up and they notified me immediately, and I was OK with it. Oconee Leatherworks, (CavScout) was another one where Steve said he needed to spend more time with his family and bowed out. But this was completely transparent and upfront. I am pretty tolerant and understanding when someone explains things and lets you know what exactly is going on.
When that does not happen it is pretty frustrating. Their is another vendor that immediately comes to mind who provided lower priced kilts
and has left many customers without product that comes to mind.

To my mind the service and communication are critical and if those are missing it is a significant issue.
