While I am more typically found at FedEx, truth be told, I use this UPS Store quite frequently for returning Amazon purchases that were bad (usually electronics that came from overseas).
I generally pop in with my prepaid label and drop off a couple packages at a time.
The clerk is always friendly and always gives me a drop off receipt with no sales pitch about any of the services they offer there.
I have even brought in pieces for the US Mail and bought exact postage for them there. They take them from you so you don't have to make a second stop.
They have postal boxes, copying and even sell things such as iPhone cases and chargers there.
Stop in if you need packing services or to send anything.
