Bed Bath and Beyond Setting Up for Earnings

We'll see this big retailer BBBY come out with earnings later this week and it appears option players are looking bullish.  Last week saw some very concentrated action in the September 75/77.5 call spread in the $0.34 range (over 4000 purchased by one buyer), looking for a massive payoff up to 77.5.   The company missed and got hammered last time around but with some strength in retailers lately this one seems a good bet.  I would tend to look at the October spreads however, the implied volatility for September is screaming.  An alternative move might be to purchase a call calendar (buy an Oct 75, sell Sept 75 for .55). Disclosure: Long Oct 75/80 vert call spread at $0.83.
