Answer:
In marketing, price discrimination refers to selling the same product to different buyers at different prices depending on each buyer's purchasing power or preferences which result in them being able and willing to pay different prices. E.g. a movie theater that charges different prices depending on the age of the movie goers.
In this case, the fact that a factory is located far away from your house might result in a higher price due to delivery costs, but that doesn't meant that it is using price discrimination. E.g. I just purchased a new refrigerator online and I had to pay a delivery fee that increased its price because the seller is from another state. I purchased the refrigerator from that retailer because it lower prices including delivery costs, but someone that purchased it from the same city will probably pay even less than me. But it is just logistics, since I live far away I have to wait 3 days for delivery and pay for it.
