MarketPage lets you create your own marketplace on Facebook enabling your visitors and fans to buy items directly from your Facebook Page. You can sell your own items and/or invite other people to sell on your MarketPage.
Not only can you make money by selling your own products, you can also make money via other sellers by charging them listing and/or transaction fees.
The app is currently available by “invite only”. Once you receive your invite, you simply install the app and you’re away.
Overall, it’s a great way cultivate an online community around your products and services.
