On our existing small trade of 3 $SPY 169 puts bought at .92 a few days ago; I did the following:

Bought to open 3 more 169 Sept13 Puts
Sold to open 6 168 Sept13 Puts
Net .08 debit

Now if SPY is less than 168 this week, we still have a shot for 100% or so gains, and if 168.50 can pretty much break even.
