I was in Fry's in Atlanta, GA yesterday and found the boxed edition of Trainz 2012 for $39.99! That's what I just paid for the download version. The boxed edition includes the printed manual so is the greater value. However you can bet Auran still made money on the boxed edition at Fry's.
I'm still happy with the way Auran provided me with a 20% voucher for the download edition (I was offered the same discount for the boxed edition as well). If I'd have paid $49.99 (US) for the download at the Auran download store, I'd have been pissed when I'd have seen the boxed edition on the shelf for $10 less.
In any case Auran's got a happy customer and handled my inquiry (after I made this forum post) satisfactorily. Customer satisfaction is important for ensuring your company's longevity.
