Every November, shoppers across the world gear up for the biggest retail event of the year: Black Friday. The promise of “70% off” deals, ticking countdown timers, and “only 2 left in stock” alerts make it feel impossible to resist.
But behind the discounts lies something more powerful than price tags: the psychology of Black Friday shopping.
Retailers know how to tap into our scarcity bias, push us into impulse buying, and exploit our fear of missing out (FOMO). That’s why so many of us end up overspending on things we don’t actually need. With holiday spending growing over 7% year-on-year, with both in-store and online purchases climbing sharply, it is no surprise that we face the dreaded January debt hangover.
But here’s the truth: you don’t have to fall into the trap. With the right approach, you can outsmart Black Friday marketing tricks, stick to your budget, and even come out ahead. Here are 7 survival tips to help you beat the Black Friday machine and protect your financial wellbeing this holiday season.
Black Friday thrives on one thing: spontaneity. The flashing discounts, the ticking countdowns, the rush of “limited time only”, all of it is designed to nudge you into buying things you didn’t know you wanted five minutes earlier. And once you’re in that zone, rational decision-making starts to slip.
This is why the simplest and most powerful strategy is also the least glamorous: make your list before the sales begin.

Think of it as armour. When you take stock of what you genuinely need: a new laptop because your old one is dying, sneakers because your running pair has worn thin, or a planned Christmas gift for your sister, you create an anchor for your spending decisions. Anything outside that list is noise.
We buy things we don’t need with money we don’t have to impress people we don’t like.
It also helps to write your list somewhere you can’t ignore it — your phone notes, a sticky note on your laptop, even a quick spreadsheet. Then, when the adrenaline of the sales hits, you have something tangible to guide you back to reason.
Urgency creates panic. It narrows our focus so dramatically that we stop asking important questions like: Do I need this? Can I afford this? Is this actually a good deal? Instead, the brain fixates on not missing out. Psychologists call this loss aversion, the pain of losing an opportunity feels stronger than the satisfaction of gaining something.
Marketers know this. It’s the dark side of digital nudging that we’ve unpacked in another post. Marketers design websites with timers that tick down even if the sale resets the next day. They send you emails saying “Your cart is about to expire” (even though it’s not). They frame stock levels as scarce, because scarcity bias convinces us that rare = valuable.
But here’s the truth: more often than not, the urgency isn’t real.

So how do you resist? The simplest counter-nudge is this: pause and ask yourself, “Would I still buy this tomorrow at the same price?” If the answer is yes, maybe it’s worth considering. If the answer is no, then the deal is the one controlling you, not the other way around.
Black Friday is often compared to a shopping holiday, but in reality, it’s more like walking into a casino. The lights flash, the pace is fast, and every little win feels thrilling: “I saved 40%! I grabbed the last one!” In the heat of the moment, it’s easy to forget that money is still leaving your account.

That’s why a budget isn’t optional on Black Friday. It’s your anchor in the storm.
Take, for example, someone who sets a Black Friday budget of R3000. They might allocate:
If a flashy “limited-time” gadget for R1200 pops up, they can ask: Do I want to sacrifice part of my laptop budget for this? That trade-off makes spending real again, instead of abstract.
Budgets also combat present bias, our tendency to value short-term pleasure (scoring a deal) over long-term stability (financial peace of mind). When you set a limit before the sales begin, you’re listening to your future self as much as your present self.
One of the sneakiest tricks of Black Friday is the illusion of a bargain. You’ll see banners shouting “Was R3000, Now R1500!” and feel an immediate rush of victory. But step back and ask: compared to what?
Here’s a real example:
A friend once bought a “discounted” coffee machine for R2500. It had been marked down from R5000. He felt triumphant, until he discovered the same model had been retailing for R2600 for months at another store. His big “win” was really just a small difference dressed up as a jackpot.
The lesson? Don’t trust the anchor; trust the data.

Reframe this with a question you ask yourself before every purchase: “Would I buy this if the original price wasn’t mentioned?” If the answer is no, then the “deal” only existed because of an anchor, not because of value.
Black Friday can be valuable if you truly need something, but only if you know the baseline price. Without comparison, you’re at the mercy of whatever number the retailer feeds you.
The psychology of Black Friday is built around one number: the percentage off. 30%. 50%. 70%. The bigger the discount, the bigger the rush. It feels like winning a prize, and for a moment, it doesn’t matter if we actually wanted the item.
But here’s the catch: a 70% discount on clutter is still clutter.
This is where the discipline of focusing on value comes in. Instead of asking “How much am I saving?” the better question is: “How much value will this add to my life six months from now?”

This mindset shift is simple, but powerful. Think about it:
Price is what you pay. Value is what you get.
Cost-per-use thinking (or girl math 😉), a far more useful metric than “percentage off.”
On Black Friday, it’s easy to confuse price and value. Retailers scream about price; very few whisper about value.
Impulse buying is one of the strongest forces at play on Black Friday. Retailers know that if they can get you to decide in the moment, they’ve won. The flashing timers, the “only 2 left” banners, the urgent emails in your inbox, they all work together to push you toward an instant “yes.”
But here’s the truth: most of those “must-have” purchases don’t feel so urgent 24 hours later.
That’s why one of the simplest yet most powerful strategies is the 24-hour rule: if you see something tempting, wait a day before you buy it. If the desire is still strong tomorrow, and it fits your budget, then you can go ahead with confidence. But if the urge fades, and it usually does, you’ve just saved yourself money and regret.

Some people even adapt this rule further:
The brilliance of this tip is that it’s free, instant, and requires no complicated budgeting tools. Just patience.
Every year, Black Friday feels like chaos. The flashing banners, the urgent emails, the social media ads that somehow know exactly what you’ve been browsing, it all seems overwhelming. But what often goes unnoticed is this: none of it is accidental.
Every element of a Black Friday campaign is carefully engineered. Retailers employ teams of behavioural scientists, data analysts, and marketers whose job is to design an environment that nudges you into overspending. It’s not just “marketing.” It’s a machine.

Let’s break down a few of its moving parts:
Alone, each tactic might be easy to resist. Together, they form a sophisticated system designed to chip away at your willpower.
But here’s the good news: awareness breaks the spell.
A reader once shared how this awareness changed her shopping:
“I used to fall for every countdown clock. But now, every time I see one, I smile and think, ‘Nice try.’ Just knowing it’s a tactic takes away its power.”
Some people even turn resisting the machine into a personal challenge, a game of awareness. “How many tricks can I spot this Black Friday?” That mindset shifts you from being a passive consumer to an active observer.
Of course, this doesn’t mean you can’t buy anything on Black Friday. It simply means you’re buying on your own terms, not the machine’s. You’re not reacting to scarcity cues; you’re acting on your list, your budget, and your values.
Wealth consists not in having great possessions, but in having few wants.
Black Friday doesn’t have to be about overspending, stress, and regret. If you prepare, set limits, and focus on value, you can shop with confidence. This year, resist the FOMO shopping trap, avoid the January debt hangover, and make your money work for you, not the retailer.
Because at the end of the day, the best deal isn’t the one with the biggest discount. It’s the one that protects your wallet, reduces stress, and aligns with your financial wellbeing.

I am passionate about helping people understand their behaviour with money and gently nudging them to spend less and save more. I have several academic journal publications on investor behaviour, financial literacy and personal finance, and perfectly understand the biases that influence how we manage our money. This blog is where I break down those ideas and share my thinking. I’ll try to cover relevant topics that my readers bring to my attention. Please read, share, and comment. That’s how we spread knowledge and help both ourselves and others to become in control of our financial situations.
