Far as I can tell, Dappered is the best in class for pointing to deals on nice men's clothing. But not every deal around is posted, and understandably so. Not all deals are front page worthy. But I've discovered I've missed lots of the Bonobos $X for $2X deals, and probably many other sorts of deals. Post the so-so or niche deals here as well as the great ones.
This includes any deals or sales you see around the net on nice clothes. Or when you see a big batch of clothing that moved from full price to sale, eg as the inventory is turned over. Or something nice on a site like Overstock. Don't worry too much if it's a great sale.
Also, if you have any good sources for finding deals, post them here. I know Slickdeals and FatWallet, but most of the clothing posted is low end, and the higher end deals are often left out.
Some crumbs I managed to dig up:
Saks Fifth Avenue in-store coupon, 30-50% off: http://f.chtah.com/i/21/682906452/O5_Email_FriendsandFamily_OP_3.jpg
Dillard's additional 40% off: http://www.dillards.com/content/Additional_Sale_NCH?splashlink=hero1_es1_092911_Cl earanceNCH
And a beautiful 9.5D white buck Chukka with red brick sole, courtesy of Mr. McNairy: http://www.epauletshop.com/servlet/the-646/White-Nubuck-Chukka/Detail
And of course, the 50% off Bonobos sale. See facebook.com/bonobos
