J. Crew is offering free shipping until Sunday, August 19 with code FREESHIP. I asked customer service what time sale items were re-stocked online. Her answer was continuously. So if your item is currently sold out (which is seems so many are!), you have until Sunday to keep checking.
Below is the Anchors Aweigh cardigan in a size xxs. The fit was fine, but I decided to pass because I needed to stick to my shopping list.
