I have been thinking about this every now and then - I, and many others, hold no loyalty to any particular ride sharing or food delivery app, and the cost to switch to the one that is offering deep discounts is almost zero. I know people who are constantly exploiting these sign up offers across many businesses that are pulling the same sort of ridiculous discounting that Uber pulled - and therefore are effectively living off investor cash.

I've always wondered what the extreme end of this could look like. It seems like here in London companies in this same area are popping up almost weekly in areas like grocery delivery, food delivery, ride-sharing, etc, and they almost all have absolutely crazy initial sign up discounts. I suspect there is an entire class of people that are effectively taking advantage of this and I wonder how much they manage to save.
