I am finally traveling with a laptop and while at MSP, thought I'd power it up while waiting for my flight. I found that I can buy 24 hrs of access for $7, but saw that they must have coupons out there. Does anyone know how to obtain these?

Does MSP do any kind of monthly service for their frequent travelers? Or is that there "gimmic" for the NW Club? I just can't see spending the money for NW Clubs ... but maybe thats only because I haven't experienced it.
