Starting at post #95. Good news is, they appear to be fulfilling orders, it's just taking a long time
In a nutshell, they are backlogged because of word of mouth, and it's the season where everyone is ordering stuff. They need to work on their PR side of the business. If it was me, I'd start with a disclaimer on their site stating possible lead times, and that communications might be slower and less, then normal.
I am not affiliated with them in anyway, just seeing the trend.
