Harry Yang is a retail seller of specialized tools. Harry has noticed that his customers have been asking for a special tool for use with septic tanks. Harry sends an e-mail to ST Tanks with the following, "I will buy 10 of your ST septic grinder pumps for $500 each. I will pay shipping." ST Tanks responds, "We can sell you the 10 ST septic grinder pumps for $500. Will ship them Thursday. Payment terms as 30 days same as cash. There are no warranties with the pumps." Have Harry and ST Tanks formed a contract? If they have, what are the contract terms? What steps would you recommend Harry take at this point?
