As the couple planned to invite lodgers, they needed a second
fridge/freezer, so naturally. They decided to find an
energy-efficient and ozone-friendly model. It was also fitted with a
SavaPlug which saves a further 20% on what is the most
energy-intensive device in the house after hot water and central
heating

Where can these plugs be obtained, are they expensive, and do they
really save that amount of energy?
Only if you really really believe that they do ....
