Thanks for your comment @theaverageman. People can list any product that they find available where it can be considered a deal/ item at a good discount. Products won't be sold directly through the site.
There will be moderators reviewing the products listed which will prevent the ability for a person to automate a bot designed to "game" the system.
We're certainly conscious of this possibility and will not be tolerating this type of activity.
