DB booking: why does 2 x 39 = 98?
In booking tickets on the DB site for my wife and I, traveling on a Wednesday in February Frankfurt to Amsterdam, I notice I can get a 1 traveler booking for 39 Euro and for two travelers it's 98 Euro (It says "Single ride not available for the 78 Euro fare). In both cases getting the Europa-Spezial Niederlande fare. On dates around the one I need I get the 78 Euro price most of the time. Is there a reason why I do not want to buy 2 singles?
