You can use regex:

var matches = /Price:(.*?) /g.exec(Price:$20 is very cheap);

if(matches.length > 1) {

    var price = matches[1];

}

else {

    // Not found

}

Note this will match any sequence of characters after the word Price:. If there is whitespace after the word price, it will break. If there is no space after $20, it will break. You need to make the rules more complex depending on your input source.
