Found a good underwear clearance deal for both men and women, flat rate shipping (order as much as you want apparently) of USD$12.95
like the above example, 3 shirts for under 16 bucks is cheap, especially for a 'branded' DKNY, of course, it will work out better if you buy more due to the fixed shipping.

the clearance is 'up to 60%', but you can knock off another 25% with the above code.
It's a bit cheaper if you order from Amazon,
