Brooks Brothers has a 25% off friends and family coupon (use code friend56) valid through 5/12. This is their largest coupon code in 8 months. Their "Brooks Buys" section is worth a look. You'll find deals like 3 Men's Dress Shirts for $199 that are now discounted even further (now 3 for $149 after the 25% off; these are normally $75 each). Their clearance section has about 300 items in it and is also worth a look.
