    options?

    For example I was considering buying some SPY March 09 Puts with a strike price of around $120.00 but I see two of them and two of other strike prices...Why ?and which one do I buy when two identical strike prices are listed?

    Example:

    Monthly and quarterly options that expire in the same month.
