Virgin's Cola's Rollercola Girl is to front a £2m TV campaign to push its i-can loyalty scheme from August 4. The ad describes how to get money off Virgin products ­ £1.50 off a CD and up to £100 off a holiday ­ by collecting six ringpulls or tokens. The company said Rollercola Girl's sassy attitude had appeal to teenagers. The scheme is also supported by press advertising. {{P&P }}
