$10.00 OFF ALL MEN'S NEVER IRON DRESS SHIRTSSurely the words "never iron" are meant to work together as a single modifier for "dress shirts," which means they're crying out for a hyphen to join them in holy adjective-ness. Otherwise, "all men's never iron dress shirts" can be read as a foreign speaker's chauvinistic declaration, along the lines of, "All women's never know how parallel park."
Personally, I regard all my shirts as "never-iron." The trick is to throw the shirt in the dryer for a few minutes just before dressing for your business meeting, then smoothing it out with a damp hand as you head out the door with bagel in mouth and coffee in hand. If you're interested, I also have tips on how to hem pants in minutes with staples and duct tape.
