According to Quinn, There are two key factors driving this unique event. First, California residents have been very good to me. California is our #1 state in artificial Christmas tree sales. In a small way, my way of giving back. Second, there are some Californians who still prefer to see a tree firsthand in a retail store. Since we sell trees on the Internet, we wanted to remove any risk those folks had, help them get over the hump and actually buy online.
