It may have started as an accident in the 90s, but today it’s one of JD’s most powerful pieces of brand infrastructure. Andrew Wiseman investigates.
On the college drop-off this morning, I saw something that I’d seen a thousand times, but hadn’t ever really thought about it. A sea of bright yellow JD Sports duffel-style bags, all heading toward the high school near the college drop-off point. Not one or two. Dozens. Identical. Loud. Wherever you looked, you could see them!
The JD Sports duffle isn’t new – I remember having one when I was 18 (and that’s a LONG time ago). But it got me thinking that JD Sports has quietly created one of the most cost-effective pieces of brand visibility in the country. Because for a retailer that spends serious money on advertising and sponsorships, the thing making the biggest impact at 8.30am on a weekday seems to be a 40p plastic bag.
So, what does this omnipresence mean? For brands? For marketing? For market research?
The behavioural economics behind a very easy choice
The bag isn’t free, but at 40p it’s about as close to frictionless as a branded product gets. You’ve bought something, you need to carry it, and for the price less than a packet of crisps you walk out with this big, bright, durable yellow thing. You don’t think about it. You don’t debate alternatives. You simply take it because it’s there and it solves a problem instantly. It carries those 80 quid trainers you’ve just laid out on.
If you’re familiar with Richard Thaler’s idea of sludge in reverse, then you’ll understand that by offering this bag, it removes obstacles to the shopper experience, rather than adding them. The simplest choice becomes the default choice.
And then there’s the colour. It is almost high-viz in its boldness. Behavioural scientists talk a lot about salience. Some cues just stick out and demand attention. This bag is one of them. You only have to see it a couple of times before you start spotting it everywhere, and once you start spotting it everywhere, your brain begins treating it as normal. It becomes social proof without anyone consciously trying to send a message.
These Zees and Zalphas aren’t advertising JD Sports. They’re carrying their things. The visibility is a by-product. But collectively, their morning routine becomes a form of brand infrastructure.
The power of simple repetition
Psychologists have long recognised the mere exposure effect. The more you see something, the more familiar and acceptable it becomes. JD hasn’t paid for extra impressions. They’ve created a product that generates them on its own.
And so these bags keep showing up. At school gates. On buses. In sports halls. On park benches. Hanging from pegs at home. Squashed into lockers. If you mapped the touchpoints, you’d probably find this humble 40p bag is one of the most frequently seen youth-facing brand assets in the UK.
Cost per impression? Practically nothing.
How this fits the challenger-brand mindset
Byron Sharp talks about two big rules in How Brands Grow. Be easy to buy. Be easy to notice.
JD accidentally ticks both boxes.
The bag is the easiest possible purchase add-on. No thinking required. And once it leaves the store, it is very easy to notice. It travels through the real world, creating moments of visibility in places no media plan could realistically buy.
Many brands chase distinctiveness through design systems, tone of voice or carefully engineered visual identity. JD has managed to create a distinctive asset by simply making something useful that people keep using.
What researchers and strategists can take from this
This is one of those observations that reminds us that brands aren’t only built in boardrooms and brainstorms. Sometimes the most influential touchpoints are the accidental ones.
A few things that this tells us:
- How customers use your brand assets matters just as much as how you intend them to be used.
- People keep and reuse things that solve a real problem. Even if they cost only 40p.
- One yellow bag is a noise. Twenty is a cultural signal.
- JD didn’t plan for this bag to become iconic. But it has.
Looking a little closer at the everyday
Marketers love new channels, new formats and new metrics. But sometimes the most powerful branding tools sit quietly in plain sight. A low-cost bag. A habitual behaviour. A bit of colour that refuses to blend in.
So next time you’re at school drop-off, or heading into a gym, or walking through town, keep an eye out for these accidental billboards. They often tell you more about the true reach of a brand than any dashboard. And in JD Sports’ case, it turns out that 40p can buy a surprising amount of visibility.
