This is exactly right. It's an old marketing trick, plays into your initial reaction with the price tag. And often times people will round it down instead of up, so $99.99 will be $99 dollars, saying "Man, I got this awesome painting for my wall, it was only $99" sounds more appealing than "Man, I got this awesome painting for my wall, it was only a hundred bucks".
