Supermarket group Albert Heijn booked 12.6% higher net sales in the first three months of this year, partly due to the takeover of a number of Konmar stores from the Laurus group in 2006.

In total, sales at market leader Albert Heijn reached €2.4bn. Parent company Ahold reported total first quarter sales of €13.1bn, down slightly on 2006. Ahold said this was due to the weaker dollar.
