Despite competition from bigger rivals Booker, Batleys and Makro, which already operate in the city, managing director Steve Parfett said he was confident the new depot would be as successful as its five other outlets.
The purpose-built 75,000 sq ft depot in the Tinsley area represents a £6m investment by Parfetts.
On its first day of trading on Monday, the depot attracted several hundred customers.
Parfett said this was a result of pre-registering local independent retailers and introducing them to Parfetts’ opening offers, promotions and its policy of ensuring a wide range of products were available.
Building from scratch has enabled Parfetts to introduce all its latest thinking, including a stepped-back shelving system, the latest chilled and frozen facilities and extensive butchery, fruit and vegetable and fresh food ranges.
One of the features that drew most attention on the opening day was direct load checkout facilities.
The depot has five, and they enable large orders to be loaded directly into a van or lorry from the checkout.
General manager of the new depot, Graham Jagger, said: “I am delighted our opening day of trading has been such a success.”
