Kansas is a pretty big state, but I found there are 2 Cookies by Design in your area .... Overland Park and Wichita. http://www.cookiesbydesign.com/shoppelocator.aspx
You might check out their website for price comparing, too. Grocery store bakeries are not a good comparison.
I did Halloween cookies. I used large cookie cutters, about 4-5 inches.
I decorted with royal icing, sanding suars, and lustre dust. I charged $3 a single cookie, $15 a 1/2 dozen. I sold 3 dozen and 5 singles. The people that bought them (at work) didn't blink an eye at the price. For regular sized cookies, about 2-3 inches I charge $10 for 1/2 dozen and $18 for a dozen. I sell them for $1.50 to $2 each. I sell quite a few at the Holidays. I am located here in the Dallas/Ft. Worth area. Hope this helps you out.
