A few years back, a man was arrested for DUI while wearing a breathalyzer costume for halloween. Oh, the irony. A good breathalyzer can help avoid that, or other perilous drinking & driving situations. For a little while, Gizmodo readers can grab one, the BACtrack S35 for 57% off – just $29.99 (its lowest price ever).

Gizmodo really likes BACtrack breathalyzers, but thinks they are too expensive. That's why we brought you this deal – a BACtrack on the cheap. BACtrack measures your BAC (blood alcohol content) quickly, and lets you know whether or not you should drive home. Plus, it's great fun at parties.

The BACtrack S35 is super-discreet – it can easily fit in your pocket and displays your BAC quickly, in just five seconds. Please remember however, that no breathalyzer is a replacement for good judgement.

BACtrack normally retails for $70 – Gizmodo readers can get it for $29.99.

We've even thrown in free shipping to the US and Canada. Interested? Head over to StackSocial:
