Irresponsible fulfillment and handling.
Product arrived damaged from Marine Fulfillment. Price was 20% higher than Amazon. Walmart...suggest you find another supplier to fulfill these orders. Feel I deserve a full refund. Will not waste my time returning this product. Will instead buy from Amazon. Very disappointing. Was hoping to be able to do more business with Walmart in the future cause I am satisfied with your user interface and online platform.
