Online private sales: where trust ends, problems begin

I often buy things online, and more than large marketplaces, I think about person-to-person listings. The negotiation is lively, you set the price, and sometimes you find things you can't get in stores. But every now and then, someone tells me a story about a friend of a friend who lost three hundred euros, and then I remember that the same freedom that makes this market appealing is what makes it dangerous.

One of the most annoying things about online purchases is that when something goes wrong, you often don't even know who to blame. The platform says it's a problem between users, the seller has deleted their profile, the bank sends you a form to fill out. If you don't have a written contract and a clearly traceable payment, you're stuck in the middle with no one to turn to.

A mental test I always recommend is to ask yourself: if this transaction went wrong, would I have the financial and psychological strength to move on as if nothing happened? If the answer is no, then that item or ticket is too important to be left to the goodwill of a stranger. You need tools that genuinely protect you, not just trust.

If a site asks you to save your card "for convenience," think twice. It's not necessarily a bad idea, but it means you're delegating that responsibility to the party in front of you. When in doubt, I always prefer to enter my details manually every time: I lose ten seconds and avoid the worry of understanding how and where they will be stored.

The right of withdrawal in online purchases is a powerful but not universal protection. It applies to purchases from professionals, with fourteen days to change your mind. It does not apply, unless otherwise specified, to private sales: what you buy from another user is not protected by the same right, and this is one of the first things we should teach those entering the secondary market.

Reviews are useful but should be read like a novel: pay attention to the rhythm, language, and dates. A profile with fifty five-star reviews all written in the same month is far less impressive than one with twenty reviews, two of which are a little critical, but spread out over a couple of years.

If you want personal advice: always start with the tools that protect you, and then discuss the price. Doing the opposite is like negotiating the paint job of a car without ever looking at the engine. Looks great, but a problem on the first long trip.
