As far as i know, quote and price mean different things
Quote can be a noun or a verb.
As a transitive verb   quote is appropriately used to describe the use of an exact wording drawn from another source. When the original source is paraphrased or alluded to, the more general term  cite is usually preferable. · The noun  quote is well established as a truncation of  quotation, though many critics regard it as unduly journalistic or breezy. As such, it is best avoided in formal literary discussions. The use of the noun was acceptable to only 38 percent of the Usage Panel in the sentence  He began the chapter with a quote  from the Bible. But the usage is less objectionable in informal contexts or in reference to less august sources; the word was acceptable to 53 percent of the Panel in the sentence  He lightened up his talk by throwing in quotes  from Marx Brothers movies. · The noun  quote is sometimes used as a synonym for “dictum, saying,” as in  His career is just one more validation of Andy Warhol’s quote  that “in the future, everybody will be famous for fifteen minutes.” This example was unacceptable to 76 percent of the Usage Panel.
