Bp.tf does not include the cost of gift wrap in pricing untradable items. Therefore, any links selling already wrapped Summer Shades have been accounted for.

Maybe a couple are successfully selling at 5 keys, but some sellers are willing to go as low as 4 keys.

Edit: You are all picky. Adding more proof.
