Amazon Warehouse is a section of the Amazon online store that offers savings of up to 50% on pre-owned and open-box products. These bargains are products that are often still in good condition but can't be classed as 'new' since they've either been used or at least their boxes have been opened.
Amazon checks each item and uses a series of descriptions to define its condition: 'like new', 'very good', 'good' and 'acceptable'. The products usually come in their original packaging, they're eligible for Prime delivery and are covered by the usual 30-day return policy. You can read about the Amazon Warehouse terms for full details.
The most difficult thing is finding Amazon Warehouse deals since they're available only in limited quantities. That means you have to do a bit of digging, but we've linked to all of the different Amazon Warehouse categories below.
