The implied warranty of merchantability is a legal concept that ensures products sold by merchants meet certain quality standards. This means that goods should be fit for their intended purpose, adequately packaged, and free from defects. For example, if you buy a toaster, it should toast bread properly and not have any safety issues. This warranty automatically applies when a product is sold, even if the seller does not explicitly state it. If a product fails to meet these basic standards, consumers may have the right to seek a refund or replacement. This protection helps maintain trust in the marketplace.
