EXPE, the October 45 puts or November 45 puts (usually get the 45's for October and if they begin to do well, add the November puts closer to the report)
ROOM the October 50 puts are good until October expiration but if you want more downside you need to pay the slightly higher premium for the November 45's. The price of the ROOM November 50 puts (URDWJ) seems a bit pricey.
