None of the above choices .Amazon did not apply the discount so the textbooks were full price .They never received the textbooks they paid for .Amazon refunded their money because they did not have the textbooks .
What happened after they placed an order ?
I recently had to order some text books through Amazon books . They had the best prices anywhere online . Text books can get really expensive so it 's nice if you can get a $ 20 or $ 30 discount .
