A QR code on special promo packs was supposed to lead punters to a new year offer for a free week at Nuffield Health.

Instead, as Surreal put it: “None of us stupid morons bothered to check the QR code”, which actually routed to Wikipedia’s homepage.

At least it was a rather more harmless outcome than Mattel’s recent ‘Wicked’ toy packaging website error that directed children to a NSFW adult website of the same name.

Surreal’s solution was to apply a sticker onto the packs, but as the team discovered, it “turns out that sticking hundreds of stickers on hundreds of boxes costs a few quid”.

Yes indeed. Hat-tip for: “The moral of the story is hire a profreader.” Hah!

Still, the brand engagement generated by the errant code will surely have paid dividends. The confession generated thousands of likes and hundreds of comments on social media, with many people choosing to share their own experiences of similar cock-ups.
