Most trades on Bichermaart go smoothly, but a few simple habits keep you out of trouble. Meet in a public place. A station, a library or a busy café works well. You never need to invite a stranger to your home. Check the book first. Open it, look at the spine and the pages, then hand over the money. If the copy does not match the description you are free to walk away. Be careful with unusual payment requests. Nobody legitimate needs your full bank login, your card PIN or a scan of your ID to buy a paperback. If a buyer offers far more than you asked and then wants a refund of the difference, it is a scam. Keep the conversation on the site until you are comfortable. Your phone number is never shown publicly on Bichermaart.
