I've talked to some of the salespeople in Beverly Hills and it seems that sale days are different for every H store in the US. I was told that the unsold sale items from the Western US stores go to Beverly Hills for its sale, and the items unsold at the BH sale end up at the NY sale, where they're joined with the unsold sales items from the Eastern US stores. So the BH sale is the last sale date for the western stores and the NYC sale is the last sale of the season for the US stores.
