Oh, neat idea for some quick prototypes if you'll be using this a lot.
String.prototype.is = function(){ var rgx = new RegExp('^' +
[].slice.call(arguments).join("|") + '$'); return rgx.test(this) }
Should mimic: /^A|B|C$/.test( $('#price_group_lesson').val() );
Called by: $('#price_group_lesson').val().is('A','B','C','D');
