Columbia takes up to 60% off a selection of its men's, women's, and kids' apparel and shoes via coupon code "2FEB60" as part of its Web Specials. (The discount is taken from the item's original price; it doesn't stack with the sale price.) Plus, Greater Rewards members receive free shipping. (Membership is free.)
There are lots of things Uncle Sam can't touch — so long as you play by the rules.
