I bet that's wrong, and that a huge chunk of shopping is from cell phones that usually have an effectively random IP when they're not at their home location.

It would be interesting to see the numbers. I know for my wife and I, most shopping is done at home on phone or tablet and connected to our home wifi. And even shopping away from home is generally in the same county, so taxes are the same (or close enough for an up-front estimate).
