Food and drink wholesaler Booker saw like-for-like sales rise by 5.4% in the 16 weeks to 31 December 2010.
Total sales were up by 7.2%, non-tobacco like-for-likes rose by 5.5% and like-for-like tobacco sales were up by 5.1%. Fruit and vegetable sales increased by 54%.
In addition to sales, Booker's number of customers and average spend per customer have also risen.
Recent acquisitions fine dining supplier Ritter-Courivaud and pub and club supplier Classic Drinks are also "performing in line with expectations".
"Booker serves over 400,000 independent retail and catering businesses," said chief executive Charles Wilson.
"They have had a difficult quarter in part due to the poor weather.
"We are grateful that they gave Booker more of their spend during this time and look forward to serving them in the months ahead."
