That's the problem with government. they think it's their money. The money he saved by not paying sales tax on a $6,000 camera will most likely be spent at local businesses, generating sales taxes there, income taxes, property taxes, and a multitude of other taxes that the business and employees pay. Maybe this is why I like buying used gear from others.
that's the problem with the typical citizen...thinking that the money to keep roads repaired, to pay for schools and teachers salaries, that pays for police and fire department protection, that pays for the sewer systems to be maintained...comes from Heaven.
If state sales tax was 5%, then spending $1000 in out of state web order theoretically saves $50, which can be spent locally, so the state nets 5% sales tax on $50 spent locally, or $2.50 instead of $50, per the above logic.
