I haven't confirmed this myself, but probably worth a try.
Half price on most Cincinnati Reds home games with this code (did not work for last game of season). Good for tickets in most sections (view level, terrace outfield, family section, sun/moon deck, mezzanine, view level, field or infield box). To redeem go to Cincinnati Reds home page. Click on green T next to game you want to purchase tickets to. Near top of page where it asks "Have a Coupon Code?" type 68RTN3961 (letters must be capitalized or will come back as not valid). Click continue and new pricing per section will appear below. Proceed with ticket purchase.
