wanderer_27: WA pays taxes unfortunately :(
My guess would be:
Alaska
Delaware
Montana
Oregon
Vermont
These States don't have Sales Tax, so I would think Amazon wouldn't collect tax in those States.
grynn: States I wrote are the tax-paying ones :) Any other state than these doesn't pay any tax according to Amazon FAQ.
You're right . . . mostly.
If you go further down it becomes quite messy and seems to also depend on the Merchant.
In short, no easy answer :)
