I was so excited when a Postnet opened up near me because it's so convenient! They offer a variety of services including notary public, copying, and shipping (FedEx and USPS). The prices are reasonable ($5 for a notary public stamp). They do charge a little bit extra for USPS services and stamps because they are not an official post office substation, but it is worth it because of the convenience. They also have greeting cards and shipping supplies.
