Are there any retail stores/outlets that sell good concealers i.e. toppik, dermmatch, etc.? I know I can order on-line, but I need something fairly quickly if possible.

If anyone in particular knows of any stores around the Kansas City or Chicago area, that would be helpful as well.

Check out your local salons some may carry them. I found XFusion (similar to Toppik) at a salon close to my house.
