I'm buying a 1997 Camry 2.2L automatic tomorrow and will change the timing belt immediately. A Toyota dealer in town has a service coupon for $229.99 to change it, what's the catch? Is it a good deal?

Here's the link to the dealer special:

2015 Hyundai Sonata 2.4L 65k M1 EP 5w30 & OEM
2000 Toyota Camry 2.2L 227k M1 AFE 0w30 & Wix
1996 Jeep Cherokee 4.0L 143k Napa 10w30 & Fram Ultra
