Back in the early 2000s so long as you were buying two or more copies of Adobe Photoshop it cost as much to hop on a 28 hour round trip plane ride from NZ to the US to buy those copies rather than purchase and download the software off Adobe's website (which was geolocked and priced to match the only local physical distributor).
With physical goods price discrimination is limited by arbitrage opportunity in moving the good from one country to another. With intellectual property licensing can tie a good to a location which means that the price discrimination can effectively be any amount.
My personal opinion is regulation should proscribe the price discrimination past some multiple of purchasing parity to curtail the worst possible abuses. Having said that it's not a major real world problem while piracy remains as an outlet for abused markets.
