besides thrift stores, Costco, the Columbia outlet at Tanger, and sale racks at places like Kohl's or Macy's.

I had a "Zeroxposur" brand winter snowboarding style jacket that i didn't love the look of, and had friends make fun of the brand name, but it lasted me like 7 years and was warm and comfortable before finally starting to fall apart and was not very expensive. Pretty sure places like Kohls and JCPenney still sell them.
