The ribbon will be cut at Dowham’s new Post Office next week.
Postmistress Parvin Begum is moving her branch to the former Price Right Shoes shop at 31 High Street, which will open as a WH Smith Local store.
The business was due to open last month but the it was delayed due to building problems.
The official opening will be held at 1pm on Tuesday, March 3.
Miss Begum said: “I am looking forward to the grand opening.”
WHSmith branded cards, stationery and gift wrap will be on sale along with a range of newspapers and magazines.
The new branch will have four counters, two openplan, one screened and a Post Office terminal. The opening hours are 9am-5pm Monday to Saturday.
