One niche
Trading cards, sneakers, retro consoles. Exactly one, until you know its prices by heart.
Reselling
Buy before everyone else, resell at market price
On Vinted a genuine bargain is gone in minutes. The entire game is seeing it first — and that is exactly the part a bot does better than you do. What it can't do is tell you what something is worth.
Automated Vinted reselling on Pokémon cards — the full strategy. Spoken in French.
The principle
Thousands of listings go up every day, posted by people who don't know what they're selling is worth. Your job is two moves: buy below market, sell at market. Finding those listings isn't the hard part. Getting there before anyone else is.
A reference price
What the item actually sells for, not what it's listed at. Completed sales are the only evidence.
Speed
The best listings are gone inside five minutes. This is the only place automation changes anything.
Working capital
Your money sleeps between buying and selling. Start small and reinvest what comes back out.
Automating the watching
Refreshing a marketplace all day is not a strategy. A monitoring tool watches new listings for you and pings you within seconds, which leaves you the only job that matters: deciding whether to buy.
Continuous watching
Your searches run permanently, including overnight and while you're at work.
UnattendedTight filters
Brand, size, condition, price range, keywords. The tighter the filter, the less noise you get.
TargetingImmediate alerts
The notification lands when the listing is published, not ten minutes later. Ten minutes is a lifetime here.
SpeedSeveral searches
You can follow more than one niche without living in a row of browser tabs.
VolumeA bot saves you time, not money. Your knowledge of prices is what creates the margin — without it you simply buy unsellable things faster. The tool used for this is Adsifast. Our full review of Adsifast sets out what it does, its limits and the right moment to start using it.
The method, step by step
-
Pick a niche and learn it
For one week, write down the real sale price of the items you're interested in. You should be able to say what a card is worth before you've even opened the listing. Skipping this week is the reason most people lose money in month one.
-
Set your maximum buy price
Start from the resale price, subtract platform fees and postage, then subtract the margin you want. What's left is your ceiling, and you don't move it because a listing looks exciting.
-
Configure your alerts
One search per item type, with your price range on it. Too broad and you drown in notifications, which means you start ignoring them, which means the tool is now useless.
-
Buy fast, but look first
Check the photos, the described condition and the seller's ratings before you commit. A bargain on a damaged item isn't one, and a bargain from a seller with three unresolved disputes isn't either.
-
Resell properly
Sharp photos on a plain background, an honest description, a price in line with the market. This is the part most people rush, and it's the part that decides your margin.
The numbers to watch
- Net margin
- What's left after the purchase price, the fees and the postage. It's the only figure that really counts.
- Time to resell
- How long between buying and selling. A $30 margin in a week beats $50 in three months, because the first one can be repeated.
- Offer acceptance rate
- The share of your offers that get taken. Too low and your prices are fantasy; too high and you're paying more than you need to.
- Capital tied up
- The value sitting in unsold stock. It sets the pace at which you can keep buying.
What you need to know
- Verify authenticity, especially on cards and sneakers
- Count buyer-protection fees in your calculation, not after it
- Never complete a deal outside the platform
- Follow the platform's terms of use
- Declare your income as soon as the activity becomes regular
- Start with an amount you can afford to have tied up
Regular reselling for profit is trading, not private second-hand selling. Marketplaces now report active sellers' data to tax authorities — DAC7 in the EU, equivalent rules in the UK since 2024 — so registering at the start costs less than regularising later. Thresholds and structures differ by country; check yours rather than copying someone else's.
Where Vinted works — and what to use if it doesn't
Vinted is a European platform. It runs in more than twenty markets, and it grew very fast in the United Kingdom, from around one million users in 2021 to eight million by 2023. Ireland came in 2025. It does not operate in the United States, Canada or Australia.
If you're outside its footprint, none of the method below is wasted. Everything except the specific alert tooling transfers to whichever marketplace is dominant where you are: eBay for almost anything, and its completed-listings filter is the single best source of real market prices anywhere; Depop for streetwear and vintage clothing; Grailed for menswear; Mercari and Facebook Marketplace for general goods and local pickup. The one thing that changes is how fast you have to be — a platform with less traffic gives you hours rather than minutes, which makes it easier to learn on and harder to make a large margin.
Whichever platform you use, check its terms on automated access before you point any tool at it. Most marketplaces restrict scraping, and the restriction applies whether or not anyone notices.
Common questions
Is Vinted available in my country?
Vinted operates across more than twenty European markets. Among English-speaking countries that means the United Kingdom, where it is very large, and Ireland, which it entered in 2025. It does not operate in the United States, Canada or Australia. If you're outside its footprint the method transfers directly to eBay, Depop, Mercari, Grailed or Facebook Marketplace — only the speed of the watching changes.
Do I have to declare reselling income?
Yes, from the moment you buy in order to resell. Selling your own old clothes is generally not taxed; buying with the intention of making a profit is trading, whatever the amount. Marketplaces also report seller data to tax authorities now — DAC7 across the EU, equivalent rules in the UK since 2024 — so the information reaches them whether or not you send it. Thresholds differ by country, so check yours.
How much money do I need to start?
A few tens of pounds or dollars is enough, and starting small is the point. Getting a $15 purchase wrong costs you a lesson; getting a $400 lot wrong costs you a month. Raise the amounts once your resale prices have become predictable.
How do I know whether something resells well?
By looking at what has actually sold, not what is listed. An item priced at £80 for three months proves nothing. Completed sales give you the market price, and that's the data to collect before you buy anything.
Which categories work best?
The ones where the brand sets the price and condition is easy to describe: sneakers, branded clothing, leather goods, video games, small collectibles. Avoid anything that takes long negotiation, gets returned over a tiny flaw, or costs a lot to post.
What is the main trap?
Buying what you like instead of what sells. You end up with stock you find attractive and nobody wants. Write down your real completed sale prices from day one — a notebook of observed prices is worth more than any tool.
Want the slower, cheaper route?
Reselling pays back within weeks but needs cash up front and a real eye for prices. If neither is available right now, search costs nothing but time.
