Wrong end is right.

The argument that web businesses must track thousands of tax jurisdictions is valid.

So is the unfair price advantage remote vendors have over their brick and mortar foes.

And localities do have the right to claim whatever sales tax the impose (don't like it move).

So what is the solution? Simple: the delivery services know how much you spent and where you live. Have them collect the tax applied with their shipping charges. Give them a token carrying charge and the problem is solved.

After all, the point of sale is the home address.
