Columbia offers its Columbia Men's Rapid Rivers II Long-Sleeve Shirt in several colors (Mosstone Plaid pictured) for $16.98. With free shipping for Greater Rewards members (Not a member? It's free to sign up.), that's the best price we could find today by $3, although we saw it for a buck less last August. It's available in most sizes S to XXL.
Retirees must stretch their dollars further and further these days — no thanks to these costs.
