Eurozone retail sales declined slightly more than expected in September driven by the weakness in both food and non-food product turnover, data showed Wednesday.

The volume of retail sales dropped 0.6 percent month-on-month, reversing August's 0.5 percent rise, Eurostat reported. Economists had forecast sales to fall 0.4 percent in September.

Sale of food, drinks and tobacco slipped 0.6 percent and non-food product sales edged down 0.1 percent.

Compared to the same period of last year, retail sales were up 0.3 percent in September, in contrast to the 0.2 percent drop seen in August.
