Yeah, some of them tried that. We call it the U.S. Civil War.There is always a change that if a state wanted to (and voted to be) they could secede (break away) from the union.
On the other hand, My back yard is right up to the RI/MA border, so I can take advantage of their 2% sales tax, and the tax holidays they have twice a year. And NH (0% sales tax) isn't that far away either...but remember that states are huge for the most part so it is pretty impractical for me to just drive to say nebraska to buy something on a whim. with that said, there are many many many residents from other states in different states at any time. it would be absloute hell to have to go through a customs like process for buying stuff in diff states
C'mon man, we're talking digital downloads...no overhead for product or shipping whatsoever. How can almost doubling the cost of binary code really be justified?
There IS overhead for digital downloads. They have to pay whatever company owns the distribution rights for that particular country. They charge however much they charge, and the prices in another country have nothing to do with it (outside the EU).
