The title really says it all - I'm visiting California at the moment, and looking to get a new 32GB iPod touch. I'm hoping to avoid the 8.5% sales tax here, and so wondering if I can get it duty free when I fly back to London through the international terminal at San Francisco. Does anyone happen to know whether any shops sell it there? Or is there anyone flying out before September 30th who can check for me? Thanks in advance for any advice!
