The Brunswick Bowling birthday freebie was one that I actually used last year. I know, it's shocking that I wasn't able to take advantage of all 100+ birthday freebies we have listed, but it's true. The bowling was fun, especially the part where I scored a strike in the lane next to mine. I fruitlessly argued I should get a 50 point bonus for pulling off that feat, but my “friends” weren't having any part of it.
Signup Freebie: Free BOGO game of bowling.
Birthday Freebie: Two free games of bowling.
