Thanks for trying to help, and my apologies if my post wasn't sufficiently clear.
Here's what would prevent normal forum settings from working for me:
We need a Mobile Read subscription list for vendor-based sales and deals -- one that tells you about new threads rather than new posts on threads you've already visited.
But for that, we might need a separate deal thread for stores.
This is something I've wanted ever since first joining this this site. In my experience, the hardware and store-wide sales get lost among threads about individual books and genres. I often find those sales days or even weeks later, especially when I'm busy.
