I'm pretty sure you already missed out on the clearance of all of those. There aren't many options left. Looks like the online Cowboys Pro Shop has stopped selling them.
Your best bet I think would be to your local mall and/or sports store and see if anyone has them on the clearance rack. I got my two premier jerseys for $29 last month from our local Cowboys Pro Shop. They always have a clearance rack if you have one in your area.
