...but I can't spec based on what promo we might have 2 months down the road.

Bryan,
Why would a promo 2 months from now affect your selling price?
When I spec an item and it then goes on sale, all I say to myself is "yay, mo money in my pocket".
Unless of cause they are running ads in magazines that end users / clients would see.
I don't normally see that with anything that I carry/recommend.
