Social media is morphing from a way for users to connect with long-lost friends to the new trend of member-only buy/sell/trade groups.
Some of the local Facebook buy/sell/trade groups have become so popular that their groups consist of over 20,000 local members. Membership requires approval by the group’s admin and is generally only open to members who reside in a specific ZIP code. But once you are “in,” you are welcome to buy, sell or trade at will as long as group rules are followed.
These kinds of Facebook groups make it easy to unload your unwanted stuff. A user just needs to snap a picture with their smartphone and upload it directly to a group’s Facebook page with details and price. Group members can post questions about an item, arrange a purchase or trade, and submit an ISO (group lingo for “in search of”).
