We are offering some wicked good deals on most of our winter products right now. While we like giving you a great deal we still have to keep the lights on and pay our staff. So we're offering the following flat rate ground shipping fees on our most popular winter gear. Even with these added shipping fees you're still paying way less than full price! All regular priced Winter items over $75 still ship free via ground in the continental U.S.
