Asda has ended trials of its on-tap Envirovend detergent vending machine in its High Wycombe outlet. An Asda spokeswoman said the machine had been removed from the store, but customer response to the trial had not yet been analysed. She added: "We haven't collated the results yet, but we can confirm that the trial was successful. Whether we roll out the machine to another store, five more stores or more than that will depend on the final figures." {{NEWS }}
