Whoever sells a commodity and stipulates that, should the buyer fail to hand over the price by such-and-such a deadline, there shall be no sale between them—there is in fact no valid sale; this form of transaction is disapproved. If, however, it is carried out, the sale itself stands while the condition is nullified, and the risk of loss remains with the seller until the buyer takes possession.
