I just bought 3 leather cuff bracelets for Christmas gifts - use PREVIEW for free shipping. Also, in the few minutes I was browsing the website 3 new things were added. It looks like they'll be adding new items all the time during the SS.

I didn't have any problems with the code. Are you on their email list? It could be that you have to be on the list. And it's definitely not a difficult one to get on. Otherwise, not sure what the problem could be. Maybe try using another browser like firefox, or clearing your cookies and temporary internet files (this always works for me on NM).
