Laws regarding advance payment contract
2121. If a person purchases a commodity by way of advance payment, he
is not entitled, till the expiry of the stipulated period of delivery, to sell
it to anyone except the seller, but there is no harm in selling it to any person
after the expiry of the stipulated period, even if he may not have taken possession
of it yet.

2122. In advance payment purchase transaction, when the seller delivers at the stipulated time the commodity which he had sold, the buyer should accept it. Also, if the seller gives something better in quality than the one agreed upon, and if it is reckoned to belong to the same type, the buyer should accept it.
2123. If the commodity which the seller delivers is of inferior quality to that which was agreed upon, the buyer can reject it.

If a commodity which was sold by advance payment becomes scarce at the time when it should be delivered, and the seller cannot supply it, the buyer may wait till the seller procures it, or even cancel the transaction, and take the refund, but as a precaution, he cannot sell it back to the seller at a profit.
