Are you a Diamondbacks or Dodger's fan here in Phoenix? Buy 4 Pepsi 12 packs (on sale this week for $2 for 5 w/ minimum purchase!) and receive a receipt message good for one Buy One Get One ticket to the Dodgers series in designated sections. Restrictions apply - while supplies last. Take your receipt to the Chase Field ticket office to redeem. Games are on July 15, 16, 17. If you pay close attention to your receipt, you’ll notice this deal!
I am not sure if there is a limit, meaning if you did two transactions with purchasing 4 if you could get two BOGO ticket deals. Could make for a frugal family fun night! Chase field now has a "cheap" concession section too with hotdogs, drinks and more for around $1.50 each!
