Through 11/22, shoemetro [dot] com has boots under $25 + free shipping with code boots. Free shipping is rare for this site. I checked the selection and see a few pairs that I would totally snag up if I didn't know for a fact that DH got me my dream boots for Christmas.
they also currently have a sale on winter boots, 30% off select styles, no code needed (also probably not eligible for the free shipping). I've gotten some amazing deals at this site, just wanted to share the current sales
