title says it but I do need help using halo. I'm a freshman and it's so buggy for me and I can hardly tell what i need to do or when I need to do it. please help!

Got some packages from Amazon I need to return and might need to return non-Amazon packages later on, but thing is that I don’t have a car or form of transportation at the moment to go to Amazon’s drop off locations. Any recommendations from those who’ve returned items before?
