Ending today, LOL Shirts discounts all T-shirts to $6.99 with free shipping during its Black Friday Sale. (Pictured is the "Gangnam Style" T-Shirt; discounted prices are as marked.) That's tied with last week's mention as the best sitewide discount we've seen from LOL Shirts since Black Friday last year. (We've seen various categories of T-shirts at this price throughout the year, but not at the same time.) They're available in sizes S to XL at this price; sizes XXL and 3XL are also available, but for 99 cents more. Deal ends November 26.
