Has anyone buy tickets on "unofficial" websites, like
http://www.stubhub.com
http://www.ticketsinventory.com
http://www.ticketsreview.com
shop.ticketluck.com
http://www.razorgator.com
http://www.ticketsnow.com
http://www.tickco.com
http://www.coasttocoasttickets.com
http://www.superstartickets.com
They seem to all have the same tickets. Do you think it's safe to buy on these websites or is it scam?

I'm looking for a ticket for May 26 in Ottawa, but Ticketmaster doesn't have any

I already have a ticket for May 25, but I'd like to go to both nights.
Do you think ticketmaster will have some tickets available between now and the date of the concert ? (I thought the concert in Quebec was sold out, but I checked last week and there are still tickets available on ticketmaster).
