They already pay sales tax in Washington state.
That is because Amazon is physically located in Washington state. Their
headquarters and some warehouses are here. They took over the big, old
public health hospital on Beacon Hill in Seattle for their headquarters.
Much of their shipping for the book business used to be here too. Until
they hired a guy from California.

He pointed out that they were in an earthquake zone. And as per cooperate
earthquake rules, you never have more than a third of your corporate
business function in an earthquake zone. So they started backing everything
up in several locations and making plans for moving people if a big
earthquake happened. And they started establishing warehouses and shipping
centers elsewhere. It was a big deal because, wherever they built, they
would have collect sales tax on local sales.

And they did. But they draw the line on a referral sale. I wonder how much
money is being lost by the state who insist on doing this. They know that
they can't charge tax to folks outside of the state. The do collect taxes on
the various businesses in the state no matter who they sell to. And they
now are losing that tax.

Apparently they are upset that they don't get to double tax the sale.
