Feedback from : De : Bronson <bronsonsblood@yahoo.com>
Enable sellers to have the opportunity to sell their WHOLE collection in 1 button as a package (user can choose a card set or brand to sell) and buyers view it. This will streamline collection selling that's typically done on Ebay but could be done on your site. With this feature have the recommended price to sell at around 30% off whatever the lowest prices are on your site to mimic what collection buying is typically.
