best way to buy...

I have raided my 2 closest hobby shops of their last tamiya spray paints. I am in desperate need of ts-47 chrome yellow and ts-42 light gunmetal. I have never wanted to resort to buying offline but what is the best way to get some new cans to me!? I cant really wait for my hobby shops to restock (I will be going off to school soon and cannot continue this hobby once I'm in school). I wanted to buy these two cans and including shipping it was over $17 online! Anyone have an suggestions?

UPS ground takes 5-7 days, so mail order isn't fast, either. A Hobby Town USA near me took only 3 days to special order a Tamiya product. Does your hobby shop take longer than ordering from a mail order store?
