Here is a partial Cafe post from a year ago:
Anyone have a promo code for CBS?

"Actually, not to be the bad guy here, CBS no longer does that promotion, Matthias. What they do now is will e-mail you a $100 coupon code for use only on CBS Sportsline leagues next year, not $100 cash/check like they did for fantasy football. You may know this, but wanted to make sure.
So, the deal is, people creating a new league get $90 off the league and the person's link they are using gets a $100 coupon code for use on CBS fantasy leagues, not products, just leagues, in, I believe, 2011. I might be wrong about when it ends or is limited to, though."
This was taken a topic started in 2008 I believe this post was on page 5viewtopic.php?t=318449&start=40
I used the CBS help link in my league and asked them if they were going to have promos for 2011 and they said they would have them again when they opened the '11 leagues for everyone but it would only be good for new leagues
