We bought tickets for the Bruce Springsteen show. We showed up at the venue with our e-tickets and everything went smoothly. The concert was Awesome! True, each ticket cost about 150% of the normal price, but it was worth it to get admission to a sold-out concert and Denver Ticket's prices were still cheaper to others offered online.
Great customer service and no fees. The price you see on the site is the price you pay. TicketProxy also has convenient downtown Denver pickup for local concerts and shows.
Trustworthy. A breeze to do business with.
