$AAOI rollout

I’m rolling this week’s in-the-money 75 puts out to the September monthly (9/15) expiration for 3.41 credit.
Bought to close $AAOI Aug 11 75 puts @ 6.89
Sold to open $AAOI Sep 15 75 puts @ 10.30
This further reduces my basis in the trade. With the 3.41 credit plus the 1.20 premium I took in for the Aug 11 75 puts my cost basis for the stock, if assigned, will be 70.39. It is currently trading at 68.33.
