Whenever it's practical, inspect an item in person before handing over any money — turn it on, check it works, look closely at the condition the listing described. This alone rules out the large majority of classifieds scams, which almost always depend on paying for something sight-unseen.
A price meaningfully below what similar listings are actually going for is the single biggest red flag on any classifieds site — it's the bait in most scam listings. That doesn't mean every good deal is fake, but it's worth being more careful, not less, the better a price looks.
Where it's available for a listing, Fyndo's own secure payment option holds your payment until you've confirmed the item arrived as described, instead of sending money directly to someone you've never met with no way to get it back if something goes wrong. Be especially cautious of any seller who pushes hard for a bank transfer, gift cards, or cryptocurrency specifically — asking for a payment method that can't be reversed or traced is one of the clearest signs of a scam.
A seller with a "Verified" badge has confirmed both their phone number and email — it doesn't guarantee the transaction will go well, but it does mean there's a real, reachable person behind the account, not a throwaway one created five minutes ago for one scam.
If a seller asks you to read them a code that was just sent to your own phone or email — for any reason, however plausible-sounding — refuse. That code is for your own account; sharing it hands over access to it, and Fyndo will never ask you to share one with another user.
Pressure to decide immediately, a seller unwilling to answer basic questions, or a story that doesn't quite add up are all fine reasons to just move on to a different listing. There's rarely only one of anything for sale.
