Ahhh price ending, it's a great practice because it makes people think they're "getting change" from the rounded off number.
For years here in Oz, KFC ran a campaign of "Feed the family for under $10"... it was $9.95. Technically, it's true, but $9.95 is still $10.00 to anyone but a hobo.
However, there's the "under $10" bit, and we stop paying attention to the rest and go "Wow! CHEAP!"
Likewise, $97 "isn't" $100 (ooh, I can still get a cup of coffee afterwards), and $497 "isn't" $500 (Oooh, this course is less than $500, what a bargain!), and a Nissan Pulsar "isn't" expensive because it's less than $15K as it's only $14,990 (drive away, no more to pay... except dealer and statutory charges, on road safety cheque, and fuel, because you don't actually have enough petrol to get to the next fuel station in the car)
