“O comprador que se cuide." (Por conta e risco do comprador)
A Latin term that means “Let the buyer beware”. It is typically used in reference to consumer transactions.
The legal principle that, unless the quality of a product is guaranteed in a warranty, the buyer purchases the product as it is and cannot hold another liable for any defects. Statutes and court decisions concerning products liability and implied warranties have substantially altered this rule.
