Revenue growth at Domino's Pizza during the Christmas period was significantly driven by online sales, which were up 102 per cent for the last six weeks of 2007.

Total online trading for 2007 was 60.5 per cent up on the prior year and reached £32.2m.

"Our strong sales performance was fuelled by the strong marketing of truly innovative new products and continual improvement in customer service times, which we know directly impact on propensity to re-order and the superior quality of our product," said Domino's Pizza chief executive Chris Moore.

In November last year, Domino's weekly web sales reached £1m, following concerted efforts to improve the firm's internet operations.

The average spend of the food chain's customers is 20 per cent higher online than for phone orders and the internet now represents around 15 per cent of total sales.
