If you ever need to receive phone calls when driving a car then it's vital not to just pick up the handset - this is both dangerous and illegal. To stay safe and on the right side of the law, the only way to answer calls is to use a hands free kit.

Most modern phones include support for Bluetooth - a simple wireless technology that allows you to connect a headset with no cable needed. And this Friday, for one day only, we've found a Bluetooth headset being sold for just £25 - that's a £20 discount off the normal price.

The BH M200 is made by HTC - makers of the Magic smartphone, as well as many other phones sold under different names (the Orange SPV, for example), and it'll be available at this low price between 11am and 4pm on Friday 10 July only. Click the jump to find out where.
