Kids Bowl Free is offering each child in your family 2 free games of bowling all summer long.
Also, you can sign up for a family pass so an adult can bowl along with them(you can add 4 names to this family pass). This is normally $30 but if you click no thanks, it will pop up a coupon code(Hot25) good for 25% off making it $22.
