Question: Acceptance. In April 1996, Excalibur Oil Group, Inc., applied for credit and opened an account with Standard Distributors, Inc., to obtain snack foods and other items for Excalibur's convenience stores. For three months, Standard delivered the goods and Excalibur paid the invoices. In July, Standard was dissolved, and its assets were distributed to J. F. Walker Co. Walker continued to deliver the goods to Excalibur, which continued to pay the invoices until November, when the firm began to experience financial difficulties. By January 1997, Excalibur owed Walker $54,241.77. Walker then dealt with Excalibur only on a collect-on delivery basis until Excalibur's stores closed in 1998. Walker filed a suit in a Pennsylvania state court against Excalibur and its owner to recover amounts due on unpaid invoices. To successfully plead its case, Walker had to show that there was a contract between the parties. One question was whether Excalibur had manifested acceptance of the goods delivered by Walker. How does a buyer manifest acceptance? Was there an acceptance in this case? In whose favor should the court rule, and why?
