Vera's Veeno is a firm of winemakers who make original flavoured wines. On Thursday, Vera's Veeno makes three sales where payment was taken on the day, with delivery arranged for the following Saturday. However, on Friday Vera's Veeno ("VV") goes into liquidation. Help me advise the liquidators on whether property has passed in the following case: Tammy owns a restaurant and contracts with Vera's Veeno for 15 peanut butter and chocolate flavoured wine cases for 600. On Thursday morning they make 25 such cases. On Thursday afternoon, Yash buys 10 of those cases. Tammy however, has decided she wants more, but upon telephoning Vera's Veeno, she is dismayed to discover the only other ten such cases they have, have already been sold to someone else. She persuades the shop assistant to give him Yash's telephone number, and she contacts him on Thursday night, agreeing to purchases Yash's 10 cases for double the price.
