Swiss half fare card for tourists

In the past, I've bought a Swiss half fare card valid for one month. Now, all I can find is the one available for 1 year and it has a higher price. Did they get rid of the tourist half fare card with the shorter duration? When I google it, I can still find it, but there is an error when I try to book it leading me to think it is a defunct link. Has anyone purchased it this year? I didn't know if it is worth waiting until I arrive and trying to get it from the train station, but I need to purchase it for 4 adults, and with the falling dollar exchange rate, it would be nice to go ahead and buy it now. I can try calling, but I thought it was worth checking here first in case I'm missing something obvious.
Thanks!
