Groupon offers a Men's Slim Fit 2-Piece Suit for $39.99 with free shipping. That's $360 off list and tied with our mention from a week ago as the second-cheapest men's suit we've ever seen. It's available in regular, short, and long sizes 34 to 50 and waist sizes 28 to 44, although not in all size/fit combinations.

Note: It ships in a random color and style.
