Do you want fries with that? We call it 'attach' - and there are some crazy examples out there:
So what next? Will BP or Shell start offering a loyalty scheme where you only buy petrol from them but you get a free car every few years?
It feels analogous to the shift towards software + services to me where increasingly you pay (more) for the service but less up front.
Got any more examples of these kind of crazy attach scenarios?
