What's a Like New item?

Like New products are often unused returns, or demo models from retail locations that just can't be sold as brand new anymore. The item may be missing the original packaging, or in the original packaging but not sealed. The item may also be a new, unused item with defects. See the seller’s listing for full details and description of any imperfections.

Some of the products may have never even been powered on, but have merely been removed from their packaging at some point. As a result, these products are heavily discounted even though you can expect them to function as if they were new.
