Selling or buying for free online is not just about choosing the first platform that comes along. Between hidden fees, recent legal obligations, and differences in how each site operates, the actual cost of a “free” transaction varies significantly. This article measures what selling and buying without initial fees really costs on the main platforms available in France.
Actual Fees of So-Called Free Online Selling Platforms
Most online selling sites advertise free registration but then apply transaction fees, sales commissions, or paid options for promotion. To clarify, here is a comparison of the main pricing models.
| Platform | Registration | Sales Commission | Transaction / Payment Fees |
|---|---|---|---|
| Leboncoin | Free | None (between individuals) | Fees if secure payment is used |
| Facebook Marketplace | Free | None (local sales) | None (cash payment) |
| eBay | Free | Variable by category | Integrated payment fees |
| Etsy | Free | Commission on each sale | Listing fees per ad |
| Vinted | Free | None for the seller | Buyer protection fees |
Free registration never means the complete absence of fees. On most of these platforms, it is at the time of the transaction that the cost appears, either for the seller, the buyer, or both.
Classified ads between individuals on sites like lepetitgratuit.fr operate on a different model: the free service covers both ad posting and connecting users, without a commission on sales. This model remains a minority compared to large marketplaces, but it eliminates the most common fee item.

DSA Obligations for Buyers and Sellers on Marketplaces
Since the implementation of the Digital Services Act in the European Union, the rules have changed for anyone using an online selling platform. These obligations apply to both marketplaces and sellers and buyers.
Every marketplace must verify the identity of a professional seller before allowing them to offer products to European consumers. Specifically, the platform collects contact details, registration information, and a self-certification of compliance from the seller. Part of this data must be accessible to buyers.
For buyers, the most concrete new requirement concerns information in case of a problem. If a marketplace discovers that a sold product is illegal, it must inform the affected consumers when it has their contact details or publish the information visibly on its interface.
The DSA also imposes compliance by design for sales interfaces. Platforms must allow sellers to provide the required pre-contractual and safety information and conduct reasonable checks after products are listed.
- Mandatory identity verification for any professional seller on a European marketplace
- Notification to buyers if an illegal product is detected after the sale
- Design of interfaces facilitating the transmission of product safety information
These provisions do not apply in the same way to classified ad sites for individuals, which do not operate as marketplaces in the sense of the DSA. However, any regular seller must consider whether they fall under the status of a professional.
Free Selling Between Individuals: Criteria for Choosing a Platform
For an individual looking to sell items without paying a commission, choosing the right platform depends on three variables that are rarely compared together.
Actual Visibility of the Ad Without Paid Options
On large marketplaces, a free ad quickly gets lost among thousands of offers. “Boost” or ranking options are paid, and without them, the useful life of a free ad rarely exceeds a few days. Platforms specializing in free classified ads often offer better visibility per ad, simply because the volume of postings is lower.
Payment Method and Transaction Security
Cash payment remains the only completely free method. As soon as a secure payment system is involved, fees apply. On Vinted, it is the buyer who pays for protection. On eBay, payment fees are included in the seller’s commission.
Prioritizing cash pickup for bulky items eliminates both payment fees and shipping costs, two items that can represent a significant portion of the sale price on small amounts.

Buying Online Without Extra Costs: Traps to Identify
On the buyer’s side, the advertised free service often hides extra costs at checkout. Service fees, delivery charges, and pre-checked optional insurance are the three most common mechanisms.
- Buyer service fees: applied by Vinted and several marketplaces, they represent a percentage of the displayed price added automatically
- Variable delivery fees: the amount depends on the carrier chosen by the seller, rarely visible before the last step of the order
- Pre-checked insurance or guarantees: some platforms automatically add a protection option that must be manually unchecked
- Customs fees on purchases outside the EU: on international marketplaces, VAT and customs duties are added to the displayed price
The final price of a “free” purchase can exceed the displayed price by more than a quarter once these fees are added together. Comparing platforms based on the total price after payment, rather than the catalog price, remains the most reliable reflex for buying online without unpleasant surprises.
Local classified ad platforms, where the transaction is completed in person, remain the only circuit where the displayed price corresponds to the price paid. This model is particularly suitable for second-hand products, furniture, and appliances, categories where shipping fees would make online selling unappealing for both parties.
