I'm selling a kids bike on Facebook marketplace and have been contacted by someone wanting to send a FEDEX collection service to get it but saying I will need to pay an insurance cost to the driver. They say they'll add it to the purchase price so I won't be out of pocket but I'm suspicious. It feels like this is a scam but I don't know how they would actually benefit. The bike is only £10 so any insurance seems excessive to me!
Has anyone come across a scam like this or am I just being overly suspicious?
