Valid Contract Formed (Sales)
Any definite expression of agreement, including conduct, that shows an intention to contract is sufficient.
Even if some terms are left open, a contract for the sale of goods will not fail.
A contract will not be enforced for more than the quantity specifice. Quantity is an essential term.
Where the parties communications do not reflect agreement, a contract may be formed by conduct, by delivery and accpetance of goods, or by payment and acceptance.
