UK retail giant Tesco is spending GBP150m (US$225.5m) on a relaunch of its Clubcard loyalty scheme.

The retailer said its Clubcard holders will be able to double the value of their vouchers against a wide range of products in Tesco stores and online.

The group is expecting to attract around one million more customers to the loyalty scheme, which was first launched 15 years ago. 

Tesco’s marketing and commercial director Richard Brasher said: “Tesco already has the most loyal customers of any supermarket and we’ve been saying thank you for their custom for many years by giving them back billions of pounds worth of vouchers to spend with Tesco or on treating themselves with one of our specially selected partners.

“Now with customers going to greater lengths to search out the best bargains it is even more important for Tesco to say thank you when they choose to shop with us. But from next week we want to say an even bigger thank you by allowing customers to double the value of the vouchers we send them, making shopping with Tesco even better value and even more rewarding.”

A TV advertising campaign in support of the launch will roll out on ITV1 during Coronation Street on 11 May. The launch will also be supported with a national press, magazine and on-line advertising campaign.
