E-contract law in U.S.

"United States basic contractual rules are found in the Uniformed Commercial Code (U.C.C.) and state judicial opinions published by the Restatement of Contracts. The U.C.C. is a set of uniformed commercial rules that have been adopted by most states. U.C.C. Article 2 refers to the sale of goods and Article 2A refers to the lease of goods including computer equipment. Thus, the U.C.C. applies to electronic contracts for the sale of goods. The U.C.C. does not apply to the online sale of services.the U.C.C. clearly applies to the online sale of goods; and it may also apply to the sale of certain electronic materials depending on the jurisdiction, the type of 'electronic material,' and the amount of service that this sale entails."
