REI cuts up to 71% off a selection of men's, women's, and kids' running gear, with prices starting from $2.73. 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, both with free shipping:
Amazon offers the Merrell Women's Snowbound Mid Waterproof Winter Boots in Charcoal for $49.99 with free shipping. That's $10 under our mention from February and the lowest total price we've seen. (It's the best deal today by $6.) They're available in sizes 6 to 11.
Note that size 8 is available for $35.55 with free shipping.
