Asof this writing, 247,186 iPhone 4/4s cases. For decorative cases I've always bought from eBay, never had a problem from Hong Kong, etc. Just takes a couple weeks.
Not to rain on your parade, but I could never see that kind of money for decorative cases. I buy one top-quality protector (Otterbox, Defender or the like), and the rest come cheapo; so cheap that if they get dirty or show wear I just pitch 'em and go with a fresh one.
