This coupon/ad for Stella Artois is hilariously genius. If you are familiar with Stella's "Reassuringly Expensive" campaign, then you know how perfect this idea is for the brand. A lot of good advertising comes from turning what's expected upside down - but a coupon that makes the product more expensive is just so wrong that it's brilliant. This couldn't be more simple, more crazy and more on strategy. Huge kudos. It also goes to show - no ad space is too small to blow people away with creativity.
