I am trying to buy a train ticket for my wife and myself this June from Munich to Frankfurt Airport. If I go to the Rail Europe website, my tickets will cost $160 per person in 2nd class. However, if I go to bahn.com, I can buy 1st class tickets for approximately $130 per person. Whenever I see a deal like that, I get suspicious. Should I here? Has anyone bought tickets on bahn.com. Or should I just wait until I get there?

Any experience or advise is appreciated.
