Ellen contracts to buy six cases of vintage Fertile Valley wine from Grapes & Vines Winery for $1,200. The contract states that delivery is to be made at Ellen's residence "on or before May 1, to be used for daughter's wedding reception on May 2." On May 1, Grapes & Vines's delivery
van is involved in an accident, no wine is delivered that day, and no one from Grapes & Vines tells Ellen. On the morning of May 2, Ellen buys the wine from Happy Hill Winery. That afternoon, just before the reception, Grapes & Vines tenders delivery of the wine at Ellen's residence. She refuses tenderdelivery. Grapes & Vines sues her for breach of contract. How is the court most likely to rule?
