"suck dry" is excessive editorializing for a practice that make sit possible for a market to exist without, well, "sucking the manufacturer dry".

Exactly, it is not an economics trick for if companies could only supply a certain level of the market it might not even be profitable to produce. It is just economics...
We are talking about chips here so not the same bottle of soap with different labels, I'd call that a trick.
If you just have one price, you cut out people who can't afford it and people who can afford to pay more get away with more of the surplus.
If you have several prices and create just enough difference in the product that it doesn't change the expense much, you can suck dry every class of user.
Bit of an MBA trick.
