Janine owned a shop selling fine bone china. After a customer dropped an expensive bowl and shattered it, Janine posted a sign reading, "Lovely to look at, lovely to hold, if you break it, consider it sold."

Wanda came into the shop one day and picked up the vase. While she was examining the vase, she asked Janine where the vase had been made and by whom. While still holding the vase, Wanda dropped it, causing it to shatter on the ground. The sign on the shelf said "$200 plus HST." Janine asked Wanda for $226, being the $200 plus HST. Wanda refused to pay for it, saying she did not mean to drop it. Janine said that Wanda had made a contract to buy the vase, but Wanda said she had not entered a contract
