REI takes up to 66% off a selection of Marmot men's and women's apparel, accessories, and gear with prices starting from $19.83. (Prices are as marked.) Opt for in-store pickup to dodge the $5.99 shipping charge, or get free shipping on orders of $50 or more. Some sizes are limited. A couple of best bets:
REI Outlet offers the Marmot Men's Thermo 1/2-Zip Jacket in eight colors (Atomic Blue pictured) for $54.73 with free shipping. That's the lowest total price we could find by $10. It's available in sizes S to XL, although not in all size/color combinations.
