A large Devon post office is being relocated about 100 yards (91.4m) to a local supermarket.
The Ridgeway branch, one of the largest in Plymouth with a full range of counter services, will transfer to the Plymco supermarket in February.
The Post Office said the move was necessary to safeguard the long-term future of the branch in Plympton.
It has not yet revealed what will happen to the existing site, which is in a prime commercial location.
Customers had raised concerns about whether the supermarket could physically accommodate the branch, but the Post Office said plans had been modified to create better access.
