There is no "business name" or address or phone number visible on the site. It has a BBB seal, but no way to check that out. I'm a sucker for a good deal, but there is noooooo way that I would give this person my credit card number!
First off the BBB logo and other graphics on the bottom are stolen from the site www.vacationsmadeeasy.com (check out the properties on these pictures and then go to the aforementioned site)
It looks like a scam, I would stick with Ticketmania or Mapleleaftickets to be honest... Why risk wrecking your vacation just for saving a few buck on tickets?
