The man from that little post office on Glen Road buys his books of stamps at Food Lion, too, when they run out...:lol::lol:
Wal Mart sells them too. Either at the registers OR if they have that kiosk type place up near customer service (the kiosk type place is where they also do mailing out of packages,etc. I've only seen a few as the stores have been remodeled)
Not sure where you work but if you are in dowtown Raleigh near the Sheraton, there is a little FedEx center if you enter the building on the Fayetteville Street side. They sell postage there.
Go on line to usps.com. We have been getting our postage delivered to our door for years now and love it. The selection is awesome and delivery is ridiculously cheap, beats getting in the car and standing in line. Try it, you'll like it.
