J Crew has an additional % off sale going on right now. I didn't find the 75% off items mentioned, but I did get the two cardigans below for $100 each with the summersale code.

It's been a few years since I've bought J Crew cashmere, but they were the best cashmere I've ever had. The featherweight cardigans are the perfect layering piece because they are so light but add extra warmth. I love them for traveling. Even after I'd worn the last one to shreds I kept it around to wear when camping. It was a crew neck and in a less ideal color, so I can't wait to get this one in navy.
