My husband loves Abercrombie & Fitch clothing, but he doesn't buy it very often because it's hard for me to justify spending so much money when you can find similar items (although the quality doesn't always compare) at stores like American Eagle, Steve & Barry's, and Old Navy. The post holiday sales are one of the few times when Abercrombie & Fitch clothing becomes affordable.
From our previous experiences, they usually have great clearance prices on their "winter" clothing beginning on December 26th. I have never seen them actually advertise their sales, and so you really have to take your chances. We have found items such as sweaters and sweatshirts that were originally $70 clearanced to $19.50. This location seems to have a pretty good selection, but it also tends to get very crowded pretty quickly and the lines at the registers can be long, so be prepared.
