How often are NM & SFA website sales updated?

Hi Ladies: It's sale time --and I'm wondering if any of you know how often the Neiman's or Saks' sales websites are updated?
In other words: how often should I be cruising the websites to see what's gone and what's been added, or reduced? Thanks!:nuts:

I think if anyone knew they would have answered. As far as I can tell, there is no distinct pattern to when they update.
