Pete Oliver, managing director of BT Consumer, said: “This is the season for that great institution, the traditional January sales. However, our customers will not need to queue on the streets for days or fight fellow shoppers to grab our lowest ever price for BT Infinity, as you just have to call BT or go online at bt.com/sale to sign up.
”We know that customers are looking to cut costs and are searching for great bargains to get the New Year off to a flying start. This year, as well as that smart TV or shiny new fridge, customers can grab a top quality BT Infinity deal that will deliver superfast speeds for the kind of price people were paying for dial-up a few years ago.”
