The “Discover the Scam” campaign conducted by has succeeded in convincing Discover Card to discontinue its partnership with the Humane Society of the United States (HSUS). In a news release announcing the victory, HumaneWatch officials noted that HSUS stands to lose anywhere from $450,000 to $2 million or more in expected revenue as a result of the decisions.

The HumaneWatch news release also noted that its supporters have a “history of activism when it comes to asking companies not to partner with the deceptive HSUS.” In previous campaigns, YellowTail Wines and Pilot Travel Centers ended joint efforts with HSUS in response to pressure from “HumaneWatchers.”

In view of the big victory, HumaneWatch has called off its campaign against Discover. If you’re one of the savvy consumers who put your Discover card on hold during the boycott, you can use it again in good faith, knowing that those dollars won’t end up in the pockets of the people trying to put you out of business.
