Both are in the Dorchester area. One is Loders forecourt site in Dorchester itself, which has been a Spar retailer since 2003.
The second is Maiden Newton Services, just outside the town, which had been operated by the Andrews family for 40 years.
Mike Boardman, Appleby Westward managing director, said: “We are delighted to be able to bring both of these great businesses into our portfolio of company-owned Spar stores.
“Olly Andrews and Lee Loder have been wonderful advocates for Spar and are outstanding examples of what can be achieved in a wholesaler/retailer partnership.
“Over the course of our relationship with them, we have co-invested several times, constantly pushing the boundaries of convenience retailing.”
