Train travel in Austria

You buy it there as stated on the OBB website:
"VORTEILScard Classic The ÖBB VORTEILScard Classic is not bound to any particular conditions. It costs 99,90 Euro and is valid for one year starting from its issuance. A discount of up to 50% is granted for all ÖBB trains, as well for many private railways (excluding rack railways and special transport arrangements). For first time orders, you need a photo and a valid official photo identification. Get the request form at a station ticket counter."

I live in Austria and have a Vorteilscard. Since I live here and travel a lot by train, it makes sense to have one. For a tourist, however, it is better to buy SparSchiene tickets online, which are always about the same price as a ticket purchased with a Vorteilscard (but without have to pay the extra money for the actual card).
