I just checked out one of my favorite stores for buying cashmere, Neiman Marcus and found that a BUNCH of their cashmere sweaters are on sale. Some are only $44-$51!!! Here's the secret:
You have to click on the "Sales and Values" tab first before you search otherwise, your search won't bring up the cheap stuff. If you search on the home page, it doesn't bring up ALL the sale stuff... Sneaky eh??
