The buying group said sales from its member depots had increased 10.5% during June, with year-to-date sales up 9.2%.
Sales of licensed goods witnessed the biggest growth, rising 16.5% in June and 11.1% in the year to date. They were followed by own label, up 16.2% and 15.1% respectively.
The company was planning to increase own-label ranges further this year, said managing director Martin Williams, with the launch of No3 Hand Rolling Tobacco and La Flamenca value-for-money Spanish table wines. Cigarette sales increased by 9.3% in June.
"These results reflect the continued importance of independents and Landmark's place as a leading supplier to this sector," Williams added. "While facing challenges to ourselves as a group, recent new members such as Drinks Inc and our ongoing recruitment drive ensure we continue to go from strength to strength."
Landmark Wholesale's figures follow that of cash and carry giant Booker, which earlier this month reported a 4.9% increase in total sales for the 12 weeks to 18 June, with non-tobacco sales up 4.5% and tobacco sales 5.5%.
At the time, CEO Charles Wilson said the results reflected support for independents when the multiples had reported flat or negative like-for-like sales in the same period.
