On May 1, you contract orally with the Johnny, salesperson with Keyboards Emporium, to purchase for $450 electric organ for your personal enjoyment with delivery to take place on July
On May 15, you ask for the delivery on June 1 and Johnny agrees. But delivery doesn’t take place on June 1. The store later tells you delivery will be on July 1 as agreed in first place. Under the UCC which delivery date is binding? Discuss. Would there be difference under common law contracts? Discuss.
