I may have to ask Mike Longo about that and see if it's not set up to notify people. Maybe it was just an oversite when creating this area or maybe the items were already in the store and will only notify you if NEW items are added that are on your list. I just added something to my want list from the regular auction section that is already listed and it didn't notify me so it probably just notifies new items.
I just sent Mike a question about this so I will let you know what he says
