I'm cheap so I always wait until about a month before the show to get the cheapest price on resale sites, even with my faves! I've never had bad seats at a concert though so it obviously works.
I read though that the cheapest tickets for Mariah's Australian tour this year were $600...She still sold out all the dates though in arenas and stadiums

I'm going to need to save up for when she does her world tour if those are the prices though
