Igor was browsing through a used bookstore when he came across a first edition of the Jules Verne book "Around the World in 80 Days" with a price tag that read $2. Igor knew the book was worth at least $5000 so he took the book to the cashier to pay. When he attempted to pay for the book, the cashier refused to take the money saying that the book price sticker was mislabeled, and it is not for sale. Igor sued the bookstore for breach of contract. Which of the following is TRUE? Question 11 options: 1) The bookstore made the offer by putting a price-tag on the book. 2) The bookstore's price tag was an invitation to treat. 3) The bookstore can't refuse to sell the book even though they are entitled to change the price. 4) No contract was ever formed because this arrangement lacks contractual intention. 5) The cashier should have sold the book because no one reads Jules Verne anymore
