Nisa has secured a five-year extension to its contract with Select & Save.

The convenience chain has more than 100 stores and has been a member of Nisa for some years. Extending its contract would help provide a “robust trading offer” for its retailers, it said.

“Select & Save has worked well with Nisa for an extensive period of time and we are delighted that our discussions with them have led to a new contract for another five years,” said Select & Save director Kam Sanghera. “The continued relationship is a mutually beneficial one both businesses and our network of retailers will benefit from beneficial terms in these hard ­economic times.”

Select & Save director Steve Jones added: “There are obvious synergies in the ways both companies ­operate for their members’ benefit and we believed that provided a healthy footing on which to work together.”

It is the third major contract Nisa has extended in the past year. In November 2010 it secured a five-year contract with North East Convenience Stores, and in June it signed a five-year deal with export company Ramsden International. It has also signed up a string of new members, including 99p Stores and The People’s Supermarket.

“We have a successful history with Select & Save and are pleased to have signed a contract, which we believe will enable the growth and development of both companies,” said Nisa CEO Neil Turton.
