The NES version of Teenage Mutant Ninja Turtles 2: The Arcade Game originally came with a coupon for a free personal pan pizza from Pizza Hut.
In the Sega Saturn hockey game NHL All-Star Hockey '98, along with other select Saturn titles there was an included coupon that was for getting $10 back from purchasing from a list of specific titles. The coupon was a mail in rebate, and had to be redeemed by mailing it in with the original dated store receipts by the date of March 31st, 1998. The specific titles that were on the list are:
Sesame Street: Once Upon a Monster
The Xbox 360 Kinect game Sesame Street: Once Upon a Monster included two coupons for Sesame Street toys. The first was for $5 off of Elmo's Find & Learn Alphabet Blocks. The second coupon was for a Sesame Street toy playset and was also for $5 off.
Both of the coupons expired on May 1st, 2012.
