As the original poster, I'm grateful for any help with this.
Check with DVD Talk. They have a forum called "Store Forum" which is exactly what I think is needed. It would be a place to express general vendor concerns--pro and con--but are not related to specific bargains or sales.
In addition to "Store Forum" they also have a "Hot Deals" for specific sales. This is exactly what we have already. We just need a general "Store Forum" or "Store Discussion" whatever you want to call it.
Thanks again!
