I would be REALLY interested to know how you measure mileage with IP.

I tried 6 IPs with one of these locator services and one was off by over
2,000 miles, one by 150 miles and 2 by 10 miles.

Again, majority of companies that have that data will not provide it to you
for free. In a case of someone like Amazon, they probably wont measure
mileage. Rather whey would flag transactions that make no geographic sense
and pull them for separate processing.
