Seriously, how do they? They have the shoddiest delivery practices I've ever seen. I have never had good experiences receiving goods shipped via FedEx. When I lived in an apartment building in a not so good part of town, a company that was shipping warranty replacement parts to me did so via FedEx. The package was simply dropped off in the middle of the apartment hallway for anyone to walk away with....and it did walk away. The company tried via FedEx twice more, and twice more the package walked away. They finally shipped it UPS and I received it. Just today, I get home from the store and find 2 CARDBOARD boxes sitting outside IN THE RAIN. No protective covering, no notice that they tried to deliver and could not. No, the boxes were simply dumped in front of the house in the rain. Experiences like this have taught me to never trust a shoddy company like FedEx for anything. They could offer totally free shipping no matter what and I'd still refuse to use them at this point.
