Price discrimination, yeah. You make cheap versions of a product for people who are very price sensitive- that is, people without much money. You still make a profit, they get a version of the product they can afford.

I did this with math textbooks in college. You can buy "gray market" books, which are versions made for foreign markets but bought by resellers and reimported to the US. They're the same exact book, but printed without color, on cheap paper in a cheap binding. This was perfect for me, since they were also much cheaper than the US edition.

If anything, the discrimination was going the other way. The only way to get a cheap copy of the book was to buy it off the gray market- the punisher wouldn't sell the cheap editions inside the US.
