Diane Leblanc is shopping at Metro in the middle of February and sees a sign saying that raspberries are only $1.29 a package. She is very pleasantly surprised

She takes two packages to the cash, where the cashier informs her that the sign was a mistake and that the price is actually $4.79. Which of the following is correct? A) Diane has offered to pay $1.29 for the raspberries but Metro (through the cashier) has not accepted her offer. There is no contract. B) The display of the raspberries with a sign indicating their price is an invitation to treat. It is only the first stage in the bargaining process leading to a contract. C) Although logically Metro has made an offer to sell the raspberries for $1.29, because of the likelihood of errors like this being made, the law makes an exception for retailers and says that it has not. D) Both B and C E) All of the above
