Merrell Women's Waterproof Boots $55

Originally $140-$150, this selection of women's Merrell Harper Waterproof Boots drop to $52.19-$55.79 when you apply the coupon code EXTRA40 during checkout at Merrell.com. Plus they ship for free. You'd spend over $35 more purchasing these seam-sealed boots elsewhere. Editor's note: I purchased my first pair of Merrell boots a few years ago, and love them. They’ve consistently maintained their warmth, shape, and tread, making them my go-to boots for cold, wet days.
