tips[4] = "Don't take a plastic bag for each purchase  - fill up one carrier before accepting another from the next store.";

tips[22] = "If you have a separate freezer, it may be possible to put it in a cool room, (e.g. garage) which will reduce your electricity bills.";
tips[23] = "Keeping the freezer de-frosted properly saves money as it then works much more efficiently.";
tips[24] = "The average shower takes about a quarter as much water as the average bath - so a quick shower is much more economical.";
tips[25] = "Washing up under a running hot tap is wasteful - using a plug in the sink, or a bowl, saves money.";
