Hanes offers its Hanes Men's FreshIQ ComfortSoft Boxer Briefs 7-Pack in Black/Grey for $12.99. Add it to cart to drop it to $10.39. With free shipping, that's the lowest price we could find by $8 for a similar 7-pack, although we saw it for a buck less three days ago. They're available in sizes S, XL, and XXL.
