Textbook Return Request - Changed Course Requirements

Dear Bookstore Staff, I am writing to request a return for a textbook that I purchased six days ago. Since my professor changed the required textbook on the first day of class, I no longer need the book I originally bought. I purchased Introduction to Deep Learning by [name withheld] White on September 1, and I understand that your bookstore has a seven-day return policy. Because today is the sixth day, I would like to return the textbook while I am still eligible for a refund. Could you please let me know what steps I need to follow to complete the return? In addition, I would appreciate it if you could tell me approximately how long the refund process usually takes. Thank you very much for your assistance. I look forward to your reply. Best regards, [name withheld]

Dear bookstore, I hope this message finds you well. I am writing to ask if it would be possible to return my physics textbook. During the first few sessions, our professor changed the required textbook, and I am now looking for the Modern-Edge Physics textbook instead. Moreover, I placed the order seven days ago, and my request number is 555-TTKS. I purchased the book for $50. I would greatly appreciate your consideration of this request. Additionally, please let me know the return process and inform me about the expected timeline. Sincerely, [name withheld]

Dear Campus Bookstore, I hope you are doing well. I am writing because I purchased a book six days ago and now I need to return it.This is because, my professor of Prosthodontics decided to change the book to another one. I would like to ask what are the policies of returning and refunding the books, is there a penalty if I turned back too late? The book that I have is about the impact of dental implants on soft tissues from the author Carranza, but now I need the book from Pereira. Thank you for your time and consideration, Sincerely, [name withheld]
