If there's a Brunswick Bowling Alley near you they have a printable coupon you can give out this Halloween for one free game. The nice part is they don't expire until November 24. Shoes aren't included, but the coupon is good for one free game per person. There's six coupons on the page so what I would suggest is printing one page in b&w  instead of color since they really only need the bar code. Then take the copy to kinko's or copy max and run off copies for around 7 - 8 cents each. It could be a fun outing for your family as well.
