I can’t work out if this is deliberate or not. If so I’d guess it’s a kind of ‘a-ha! got your attention’ or it’s one of those deals where the sofa has actually gone back up in price since a recent sale and the advertiser is obliged to reference this (by the way that’s exactly what supermarkets do all the frigging time – hit them where it hurts steal a flat-screen telly, it’s the only language they understand).
Either way, this is very very odd. It’s only by chance that I noticed it. What do we think? Deliberate macguffin, small-print obnoxiousness or silly mistake?
