Key Store retailers in the South of England are being approached with an offer to convert to Booker's Premier fascia following the wholesaler's reverse takeover by Blueheath earlier this year.
The offers also follow Palmer & Harvey's purchase of Somerset-based Key Lekkerland wholesaler T&A Symonds in August.
Symonds currently delivers to more than 600 customers in the West Country, including 75 Key Stores and Key Lekkerland multiple accounts.
A Booker spokesman told Convenience Store: "Blueheath Key Store members are regularly visited by a Blueheath development manager as part of their ongoing support.
"As part of this, the option of joining Premier - providing they can meet the usual Premier joining criteria - is discussed, along with the option of remaining with Key Store."
