Personally prefer it over any other method - the most comfortable pickup in a mid-sized city, given somewhat irregular office hours. I've noticed some friends were having serious misgivings about trusting this method of delivery, but having tried it once, loved it. Apparently for 2017 it was apparently 22% of buyers, over 11% in 2015. [1] Worth noting is that the same service provider (Inpost) also handles courier delivery and pickups at gas stations and other such.

As for sellers, surprisingly not every one is providing this option yet.

edit: Notably some models of the parcel lockers welcome users with rather heartfelt messages - and count and show the short time it took to pick up the goods. Those trivial functionalities makes it so much more joyous to use.
