Customers often return items to retailers because of buyer's remorse. The items are often sold as an open box item even though the item is still in mint condition. Before it can be resold the item is examined to ensure it works properly. Some items will arrive in a regular retail box and some will come repackaged in a plain brown or white box. Some of the best deals can be found on open box items because the price you pay is much lower than the retail price.
