All our items can be tested before purchasing. Simply ask a member of our staff to test the product for you. Once the product is tested and the customer approves, that is a final sale. We do have a return policy. The customer has 24 hours from the purchase date to return merchandise for store credit only if the item is defected. We do not allow returns or exchanges of items that are in good or working condition. We are a liquidation store meaning we buy direct from big box retailers. We purchase all of their damage box, return items and overstock items in bulk and make it available to the public at deep discounted prices.
