I created a facebook group for people to list there used wedding items to sell to brides that need them. feel free to list your own items or join the group to find items you need. Please give it a few weeks to pick up it is a newly created group but i'm sure you will start getting results selling and buying soon. add other friends who might be interested to help make it more successful. here is the link
