I work in Summerlin and this is a convenient PO for dropping off packages. The line can get long but when I've gone in the early afternoon, they're fairly well staffed and employees are friendly. I've been in and out under 15 minutes, which isn't bad considering lines at other locations. Double check online if you're sending packages, the flat-rate box may be a cheaper option than using your own- and you get $1 off if you're sending to an APO!
