I wasn't aware that post offices could be reviewed on Yelp, but here it is. This place is great to send your mail, pick up your mail, and even get a P.O. Box. The staff are friendly and not in any hurry so you know that they will get your order right. As others have said (the two other reviews), the parking lot fits seven (7) cars (maybe nine [9] if you have a couple of those miniature cars) and the location is in a drearier part of El Mirage.
