A place for private individuals to advertise anything you have for sale, or to see what's on offer if you're looking for something.
The B&B is not for business use. You're quite capable of setting up your own pages.
Remove your posts once you have sourced or sold items. Please do not leave it until you receive payment - it's not hard to write down someone's contact details. Do not comment on posts unless you wish to purchase an item, or find out more about it, or can help out someone asking for something.
Play by the rules or you will be removed from the group.
