Hertz - help with MSP rental

I'm looking for a rental out of MSP (Minneapolis) for 11 days at the end of Aug. - beginning of Sept. I need a mid-size or larger. I have #1 Gold membership, as well as AAA and AAdvantage. The best I can seem to quote online is $366 or thereabouts, using AA's PC 947962 ($20 off per week plus 350 bonus miles). Any other discounts and/or tips on getting a better rate?

Thanks!
