While I was signed up for a couple, I already have great MC hoodies, long and short sleeved shirts, as well as PL shirts from previous GBs generously run by Jamie.
That being said:
Lots of people (like me) already have lots of these shirts
The Holidays are coming up
Some people are having tough times financially
Some people aren't interested
Those things don't make people "not too bright". I think your call out, while maybe well intentioned, is way off base.
