Every year it’s the same story: Black Friday approaches, promotional emails flood your inbox, and the temptation to buy “because it’s cheap” becomes irresistible. Many people enter Black Friday with good intentions and leave with maxed-out credit cards, installments lasting months, and products they didn’t really need.
But Black Friday can also be a real opportunity to save money — if you know how to take advantage of it. This guide will prepare you to shop smart, identify genuine deals, and leave the date with more money in your pocket (not less).
Black Friday: Opportunity or Trap?
Black Friday originated in the United States and has become one of the biggest retail dates worldwide. But each country’s version has its own peculiarities — not all positive.
The good side
- Real discounts exist: Some deals are genuinely good
- Planning is possible: You can prepare in advance
- Easy comparison: Many sites and tools help
- Ideal timing: Great for early Christmas shopping
The bad side
- “Black Fraud”: Many discounts are fake
- Time pressure: Artificial urgency to buy
- Limited stock: Many products “sell out” quickly
- Tempting installments: Makes it easy to spend more than you should
The truth
Not every deal is good. Not every deal is a scam.
The secret is knowing the difference and, most importantly, only buying what you were already going to buy anyway.
The “Black Fraud”: How to Identify Fake Prices
The most common practice is simple: raise the price weeks before and “give a discount” on Black Friday — buying at “half of double.”
How it works
Real price in September: $100 “Inflated” price in October: $160 Black Friday price: $120 (25% “discount”)
Result: you pay $20 more thinking you saved $40.
How to identify it
1. Track prices in advance
- Use tracking tools (we’ll see them later)
- Compare price history
- Be suspicious of absurd discounts
2. Be wary of extreme urgency
- “Only until midnight!”
- “Last 3 units!”
- “Exclusive discount for 1 hour!”
3. Compare across multiple stores
- The same product can have very different prices
- Marketplace is sometimes cheaper than the official store
- Physical store may have different price than online
4. Check reputation
- Review sites
- Product ratings
- Other buyers’ experiences
Warning signs
| Sign | Meaning |
|---|---|
| Discount above 70% on electronics | Probably a scam or defective product |
| Unknown site with very low prices | High risk of fraud |
| Only accepts bank transfer or direct payment | Could be a scam (no card protection) |
| Pressure to buy “now” | Manipulation tactic |
Preparation: 30 Days Before Black Friday
Those who prepare in advance have the advantage.
30 days before
1. Make your wish list
- What do you REALLY need?
- What do you want but don’t need?
- What’s the priority of each item?
2. Research current prices
- Note the price of each item on the list
- Compare at least 3 stores
- This is your “reference price”
3. Define your maximum budget
- How much can you spend in total?
- How much for each item?
- Where does this money come from?
15 days before
1. Set up price alerts
- Use monitoring tools
- Get notified when prices drop
- Compare with your reference price
2. Register on stores
- Some give early access to registered users
- Keep payment data saved (faster checkout)
- Enable notifications from stores you trust
Day before
1. Review your list
- Do you still want everything?
- Are the prices good compared to reference?
- Is the budget still the same?
2. Prepare technically
- Update store apps
- Check card limit
- Have payment data ready
Wish List: Only Buy What You Already Wanted
The golden rule of Black Friday: if you didn’t want it before, you don’t need it now.
Why this matters
The biggest Black Friday mistake is buying things you were never going to buy, just because “it’s cheap.” Saving $40 on something you don’t need isn’t saving — it’s spending $60 you weren’t going to spend.
How to make the list
Ask for each item:
Would I buy this without a discount?
- If not, you don’t need it
Where will I use/store it?
- If there’s no place, you don’t need it
How long have I wanted this?
- Wanting for more than 3 months = probably real
- Wanting for 1 week = probably impulse
Can I wait another 6 months?
- If yes, maybe it’s not a priority
Categories for the list
I need and will buy (with or without Black Friday):
- These are the best candidates
- Compare prices aggressively
- Worth waiting for the date
I’ve wanted for a while, but can live without:
- Only buy if the discount is REALLY good
- Have a defined price limit
- No long installments
Would be nice to have:
- Only if budget allows
- Pay cash or maximum 3 installments
- If you can’t get it, life goes on

Setting Maximum Budget
Without a limit, the risk of overspending is huge.
How to define it
1. How much do you HAVE available?
- Don’t count money that doesn’t exist
- Don’t use emergency fund
- Don’t max out your card
2. How much SHOULD you spend?
- Consider your other bills
- Remember upcoming expenses (taxes, holidays)
- Be realistic
3. How to divide it?
- Set maximum value per item
- Set maximum total value
- Include margin for shipping
Practical example
Total budget: $400
| Item | Maximum Budget |
|---|---|
| Phone | $240 |
| Headphones | $60 |
| Gift for spouse | $80 |
| Margin/shipping | $20 |
The “over budget, don’t buy” rule
Set limits and respect them. If the phone is $260 and your limit was $240, don’t buy it. The limit exists for a reason.
Comparing: Physical Store vs Online vs Marketplace

Installments on Black Friday: When It’s Worth It
Installments are a tool, not a gift. Use with care.
When it’s worth paying in installments
1. Real interest-free installments
- Compare: installment price = cash price?
- If yes, you can pay in installments guilt-free
- If not, calculate the real cost
2. Fits in monthly budget
- Add up your current installments
- Does the new one fit?
- Will it fit for the next X months?
3. It’s something you need now
- Don’t pay in installments just because “you can”
- If you can wait, wait and pay cash
When NOT to pay in installments
1. If you already have many installments
- Rule: installments shouldn’t exceed 20-30% of income
- If you’re already at the limit, don’t add more
2. If there’s interest (no matter how small)
- “Just 1% per month” = 12% per year
- Rarely worth it
3. If it’s to buy more than planned
- “I can take 2, it’s just $20/month”
- No. Take 1 and pay less
The small installment trap
$20/month seems like little. But:
- 12x $20 = $240
- If you do this 3 times = $720 in commitments
- For 12 months, that’s $60/month locked in
Installment is debt. Treat it as such.

3. Did you go over or stay within?
