If your church has physical goods it no longer needs, selling those goods online can be a way of giving those possessions new life. Facebook marketplace and eBay are both effective platforms for selling unwanted goods.
Facebook does not facilitate transactions, but provides a place for sellers to advertise their goods, leaving the details of any sales, such as the price, shipping and other logistics, to the buyer and seller.
eBay is a well-established online marketplace. To sell an item you must register for a selling account. You will be required to add a payment method for eBay selling fees or charges. Fee information can be found on their website.
