The best deal

When it comes to getting in the gadgets, from that flash alarm clock to your basic cooker, the cheapest price doesn't necessarily mean you're getting the best deal. Quite simply, anything that you need to plug into the wall has the potential to send you flying across the room with your hair sticking out at right angles. Dodgy electrics can cause house fires, and even kill, which makes that few extra quid worth spending, and from a legitimate source.

Where to buy?

It pays to shop around. You'll find electrical goods almost anywhere: from the high street to the classifieds, online or off the back of a lorry. If you're buying something brand new, from a legitimate trader or shop, then you have certain rights, under the Sale of Goods Act 1979. The product must comply with recognised safety standards and come with a receipt as well as full instructions for safe use.

Without this kind of cover, you could be buying goods that don't come up to scratch. A private seller is not allowed to mislead you, but you could still be sold a death trap so long as they're upfront about any faults or shortcomings. If you insist on being a car-boot sale kind of consumer, you'd be advised to avoid goods such as irons and electric blankets, and have a trained electrician take a look at anything you plan to buy.

Warranties

A warranty is basically an extended guarantee on new goods, beyond what the manufacturer offers. A PC might come with a twelve-month guarantee, but at the time of purchase you may be offered the chance to cover it for an extra two years, at a price. Before you sign up, however, ask if the cost of the warranty is likely to exceed any possible repair price. In many cases, you might find it's cheaper to take your chances.
