I'm not sure if everyone has heard but there's a new-ish brand with GUESS?, Inc. called GbyGUESS.  I'm friends with their GbyGUESS and GUESS brands on Facebook and they share their online sales really early on Facebook (I haven't looked for Marciano, their high-fashion sales yet).  Their sales this Thanksgiving are AMAZING!  I don't know if I've ever seen GUESS with such large sales.
 
Happy Thanksgiving everyone and happy Black Friday Shopping!  I hope this helps  :]
