In that case, perhaps when DAZ lists a new DAZ Original in the store, perhaps DAZ staff (and, ideally, any vendors with items introduced in the DAZ store) could post an announcement in the Commercial thread, and be Strongly Encouraged to include sales pricing end dates in the announcements? Otherwise, we have no way of knowing when it ends.
Just as an example: I would like to purchase the Supersuit once the display pricing approaches sanity (seriously, I’ve seen the Pro bundle with four different prices so far) and ideally, once the dust on the store has settled a bit. But I don’t know whether or not I have the time to wait for that, or how much time I really do have. A post in the Commercial forum about the Suit and related products with sales end dates in the first post would help a lot of people figure out when they could purchase it.
