As one of its daily deals, Hobo Ninja offers this Marvel Men's Distressed Dirty Punisher T-Shirt in Black for $7.99 with free shipping. That's $15 under the lowest total price we could find for a similar T-shirt elsewhere. It's available in size S only. Deal ends August 4.
Jos. A. Bank cuts up to 79% off a selection of its men's underwear and T-shirts. Shipping starts at $5.95, but orders of $50 or more qualify for free shipping. Size availability for some items is limited. A couple of best bets:
Walmart offers the Fruit of the Loom Men's Short-Sleeve Pocket T-Shirt in 13 colors (Black pictured) for $3.58. Choose in-store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by $2. It comes in sizes S to XL, although not in all size/color combinations.
