Just knocked £1.50 a month off my mobile bill with a phone call.
Sky emailed me to offer 25% off a "second tariff." I already have a second tariff, which I pay full price for. So I rang them and asked them to give me the discount on the tariff I already have. Which they did. Took 5 minutes.
Not going to fund a holiday anytime soon, but the joy of sending that £1.50 back into TBB every future month for the sake of 5 minutes work has made me smile 😊
