If you are not familiar with Openbazaar you can read their getting started blog post or the reddit discussion
Here's a quote that sums it upx:
Quote
If you’re not familiar with OpenBazaar, it’s a decentralized peer-to-peer network for trade that uses Bitcoin. That trade happens directly between buyers and sellers with no one in the middle – and no fees or restrictions on trade.
Some people wonder how they make money if they don't charge fees. It's because Openbazaar isn't really a company, just a platform for users to buy and sell
Quote
Because there's no company or organization running OpenBazaar, there's no one to charge you fees to list your products and no one to register an account with. The "terms and conditions" of the trade are up to the buyer and seller individually, not a one-size-fits-all policy. It's like buying or selling with someone in person - except you're online.
