Selling wine?

Hi, I’ve had a couple of bottles of wine which I’ve been trying to sell but not sure where to start!
I’m a complete newbie and I would appreciate any feedback/ guidance.
I’ve searched online however the first company that I’ve contacted has asked me to send them the bottles and I will receive the money later – I find this very dodgy and didn’t like the idea of giving them upfront (this happened 4 months ago and that guy still calls me)..
PS: I don’t even know how much should I charge for these bottles…

Any suggestions please?
