Not great prices, but there it is. Free shipping if you have a Cabela's Club Visa card and use the code "3TURKEY". I got a Cabela's Visa just for this a few months ago...free shipping makes a few purchases justifiable.
If you don't have a Cabela's card, $5 shipping on $99 or more purchase with code "3HOLIDAY".
Maybe not great if you don't have a Cabela's Visa, but there it is...
