Expensive in terms of cables or connectors?

In both cases, I've been paying considerably less for USB-C (cables and chargers combined) than for proprietary replacement chargers.

My favorite thing about USB-C charging is that (at least Macbooks) it works even with lowly 5W chargers in a pinch! Sure, it takes more to fully charge a laptop that way – but I can sustain my Macbook Pro's charge with an 18W phone charger on an airplane no problem.
