Macy's takes 15% to 20% off a selection of clothing and accessories, home items, beauty items, and more as part of its After Christmas Sale. (Coupon code "JOY25" cuts $10 off orders of $25 or more.) Pad your order with a beauty item (they start at $3) to bag free shipping; otherwise, shipping adds $10.95. (Orders of $49 or more bag free shipping automatically.) Deal ends January 1. A couple of best bets:
American Rag Men's Colorblocked Hoodie for $21.60 ($23 off)
Charter Club Damask Supima Cotton Sheet Set from $39.19 (pictured, at least $31 off)
Making even one of these mistakes can easily cost you tens of thousands of dollars.
