Walmart discounts a selection of Hanes apparel, socks, and underwear, with prices starting at $5. Choose in-store pickup on most items to dodge the shipping fees, which start at $5.99. A couple of best bets:
Hanes Women's Sport Performance Fleece Jogger Pants w/ Pockets for $14 (low by $3)
Hanes Men's Crew Top & Jogger Pant Lounge Set for $14.40 (pictured, $3 off)
Before you spend another dollar on items and services like these, check with your public library. You will likely be surprised by what it offers for free.
