5000km, 10000km and 20000km service intervals

My 5,000km service was done in Nov 2010. That one cost $100.35 for oil change, oil filter and some other not important items like battery protector and battery water and windshield washer.
My 10,000km service was done in Jan 2011. That one cost $143.15 for the same items above but with cabin filter replacement again.
The recent 20,000km service was done in May 2011. That one cost a bit more, $337 for the similar items above plus additional ATF change.

My Odometer turns 22222 km just before July 2011. I guess i am destined to be a high miler car. More than 20000km in less than a year. But since Mr. A is prompt with the service intervals, that should be okay for me.
