According to Direct Action Everywhere:

"San Francisco’s fur ban went into effect on January 1 this year, but as the new year started, Saks Fifth Avenue did not put away the fur. They are claiming to have taken advantage of a loophole in the law. They claim that the fur they have for sale was purchased prior to March 20, 2018 when the fur ban was passed, which would allow them to sell the fur until the end of 2019.

"However, when Almira Tanner, who is a member of the Direct Action Everywhere (DxE) Steering Committee and DxE’s sister group Compassionate Bay, and other activists went into the store to see if it is compliant with the law, the managers of Saks Fifth Avenue failed to produce invoices that would prove that their fur was compliant."
