On the Hautelook Armani sale today, the items say "Cannot be shipped to California". Wierd but true. The really strange thing is that Hautelook already charges tax for California so I don't get it.
Amazon's deal with California is to begin charging sales tax in Sept. California also has some uniques laws regarding shipping of certain items. Items made from python cannot be shipped to California. Also there are stringent rules on lead content, I believe it's Prop 65 that states that lead content must be disclosed on items shipping to CA.
