Arrangements that subsidize a large purchase (printer, paper towel dispenser, coffee maker, razor, smartphone, tractor, etc.) by locking the purchaser into an exclusivity agreement for consumables from the same company (ink, paper towels, coffee pods, razor blades, smartphone apps, tractor maintenance, etc.) are as old as these have been feasible. This innovation tremendously benefits both parties. I'm not sure why you'd dispense with it really.
