Except that they are not... a book on Amazon may cost $10 and a book at your local Borders may cost $10. At your local borders sales tax gets collected, and the book ends up costing $13. When you purchase it on Amazon you pay $10, and are then supposed to declare that you bought the book and pay a Use Tax. That Use Tax for a $10 is $3. You as a consumer are now obligated to pay the state $3. Having a business collect sales tax for a state it has no presence in is not in accordance with federal law, and California law does not apply due to interstate commerce laws. Thus there is no way to force Amazon to collect tax for sales to California residents. -- Go tell the consumers to pay taxes for all of the stuff they have bought, it is the consumers who should be paying the taxes and aren't.
