Pre-owned Items
Pre-owned describes products that have been purchased, opened, and operated. Then, for a multitude of reasons, from buyer’s remorse to functionality, the product is returned to the store. When a pre-owned product is processed by Cowboom, it is tested for power and basic functionality. When buying an item that is not brand new, ask yourself these questions:
1. Factory refurbished or Refurbished items frequently come in store-like packaging. This is usually noted in the item’s description.
2. How much visible wear are you comfortable with? Pre-owned items and certain grades of refurbished items may have visible imperfections. If you are planning on putting the item in a protective case, this may not be as important to you. Or if you are particularly hard on your items, the cosmetic condition may not be as important as having a device that works. Usually, the more scratches on an item, the better the deal you can get
