I may have been recalling MarksCart's conversation in CC5 about changing a $0.00 price to say something specific, like FREE! or CALL! I may have been falsely recalling where the conversation was located that allowed for the changing of the $x.xx to something else (although I know I have done that for someone somewhere) - specifically dealing with making a template change that uses the Tax class to strip off the currency symbol, testing for x.xx, then replace with a different phrase.
