I've seen them on sale actually in stores. One place that comes to mind is Barney's at Woodbury Commons. They usually have loads of GV available including oxfords, and are normally priced between $60 and $100.
I wanted to take this opportunity to formally introduce myself to the thread. My name is Chris and I'll be taking over the thread for David. I work on the Men's Buying team so if you have any questions feel free to post here or send me a PM.
