My spouse went to purchase tickets for Once the Musical and believed he was on the Des Moines Performing Arts Site. However, rather than through Ticketmaster, he purchased through GoodyTickets, which charged us $144 for tickets that are worth $63.50 a peice. They then charged an additional $40 and other stuff on top of that.
My understanding there is no recourse to this after I called and was told about disclaimers on the website. Be sure you are always buying from the website you want, - this also happened to my mother in law who thought she was ordering flowers from a local florist in my town, and instead it went through Teleflora which sent me crappy grocery store flowers. Goodytickets whould be illegal.
