Whether between merchants or not, if the parties claim that there is a valid contract, although there are conflicting conditions, the Single Code of Trade will consider that there is a binding contract between the parties. The conditions, the conflict will not be considered part of the treaty. On the contrary, the Tribunal will insert “reasonable” terms in their place. Each binding contract consists of three fundamental elements: offer, acceptance and consideration. In this module, we study offer and acceptance, which constitute mutual consent, the cornerstone of a contract. Companies can enter into contracts on terms and on all the terms they choose. They can attribute the risks within their contracts to their liking. It is up to the parties to decide what risks they are taking and under what conditions. While a supplier cannot stipulate that silence is considered an acceptance and thus imposes a favourable refusal obligation on the bidder (Felthouse/Bindley (1862) 142 ER 1037), it is possible: in some cases, waive the obligation to notify for acceptance – usually where it would not be economically practical to require such notification – as in the case of reward (see , z.B. Carlill) All this means that the exact contractual relationships will change the market place to the market place and from one e-commerce provider to another. If the law has requirements for one type of contract, they are usually that the agreement is registered in writing and signed by one or both parties or their agent. In general, price offers or price lists alone are not enough to make offers.  On the contrary, a legally enforceable contract arises only when an order is placed “in accordance with the proposed conditions.”  Therefore, the order is considered an offer.
In most cases, the transaction is not completed until the contract is signed.  So if you see a price on an e-commerce site, it`s not yet an offer. If you order the product, make an offer that the retailer can accept or refuse (z.B. if the product is not in stock or if the price has increased). If the distributor confirms your order, it is an acceptance and a binding agreement. If the language used by the parties to reach an agreement is so vague and imprecise that a reliable interpretation of contractual intentions is prevented, it is unlikely that there will be a contract. As a general rule, the death (or incapacity) of the supplier terminates the offer. This does not apply to option contracts. There is also a disadvantage to contractual freedom.
Courts expect companies to understand the legal effect of the documents they sign and commit to. In that case, there was no offer, although the applicant promised to leave the offer open. The promise to leave the offer open was unenforceable, as it was not supported by a consideration. In other words, the promisor had received nothing precious in exchange for the promise to keep the offer open.
