Roger that - that's what we do!
I'm a HUGE fan of TireRack for buying tires. You can shop locally, but 90% of the time, their price and selection clobbers the locals (and you get fresher tires!)
With that said, keep in mind the INVOs I reviewed in 2008 were cutting-edge at the time. In 2015, I'm not sure they'd be my #1 choice. I'm a fan of the Hankook Ventus V12, among others. Read some reviews, and pick what makes sense for your climate, driving style, and budget.
