We're lucky here in Pittsburgh. All of the libraries in the county are hooked into one system and we can go online (or in a branch) and request anything at any library. We can then have it delivered to any library and return at any library. All of this at no cost. This includes over 40 distinct community libraries. If it's not checked out then it takes maybe 3-5 days max to get to where you want to pick it up at.
None of the libraries charge for dvd rentals at this time (that I'm aware of).
When it comes in, they will call. We can pick it up at the drive up window so we don't have to get out of the car.
We've also had terrible luck with them. Filth and scratches seems to cause issues with our machines.
