The service at the Afton Post Office is outstanding. They are always helpful and make suggestions to save postage or make shipping more efficient; they point out when the better shipping option is only a few cents more. They even offer tape, unlike other post offices, which force one to drive all the way home to get it. The best thing is that The Afton Post Office is close, and not way off the beaten track, like Woodbury's and Cottage Grove's Post Offices.
