We all love a night out with a few drinks but sometimes we need to know when we've had too much, like if you're considering trying to drive. Stay safe...

We're offering you a digital keyring breathalyser for just £3.99, saving you 88% compared with Amazon's price of £32 (correct as of 28.4.16).

Waiting anxiously for a taxi in the wee hours is bad enough, but thinking you're sober enough to drive when you aren't is much, much worse. But how can you be sure? Today's deal is a practical bit of kit that will make a useful tool on a night out. Over the summer, the 'perhaps another splash' mentality can sometimes throw caution to the wind - understanding your alcohol levels can be the difference between a great night out and a tragic one. Simply breathe into the discreetly sized mouthpiece which aims to indicate warnings of your alcohol levels on an LCD screen. You'll also get four reusable mouthpieces included. Better safe than sorry...
