Costco offers its members the Nicole Miller Women's Metallic Yarn Cardigan in several colors (Black pictured) for $16.99 with free shipping. (Non-members pay an extra 85 cents.) That's a very low price for any Nicole Miller women's sweater; 3rd-party sellers on eBay charge at least $20 for this style. It comes in sizes XS to XXL.

Note that some sizes and colors may be backordered until December 13.
