Staff is typically always friendly and I'm in and out within minutes. However I am usually just dropping off packages. They do have some stringent box regulations that make you question how come it's ok for them to deliver and ship damaged boxes but a box I'm trying to ship has a tiny, minuscule hole and they want you to pay $14 to repackage it (box and labor cost lol).
It's super legit now that you can drop off boxes at Walgreens as well!
