Of course. It's an old trick. Create a dependency, and then soak the buyer for every penny you can get. Kodak did it years ago with cameras and film. All the printer makers do it with printers and ink. Americans are idiots that think market competition stops this sort of exploitation, but it doesn't and it never has. Every vendor will charge whatever the market can bear, so it makes no difference how many vendors there are, they aren't going to compete for the lowest price point. They're only going to compete for the highest.
I switched to a Braun electric shaver years ago because I wasn't going to pay the insanely jacked up prices being charged for razor blades that cost pennies to manufacture.
not wanting to digress the thread....but...btw
an ex-employee of a telephone assist company...
answers the call to help unsavvy printer users to get the damn thing up and running
and while doing so attempts to sell cartridges
his integrity put him out the door and unto youtube
on his screen he could see the cost of the cartridge......56dollars
and the cost of making the item......56cents
(approx.)
and your printer is rigged to know when to buy another round of ink.....AND
it knows when or if you attempted a refill on your own.....AND
will play stupid for that effort
hence the phone calls for help
