I order 3 books on 08/31/2021 including: "The Paris System for Reporting Urinary Cytology", "The Bethesda System for Reporting Cervical Cytology", and "The Bethesda System for Reporting Thyroid Cytopathology". I was expected to receive these books on 09/09/2021 which was no problem at all. I received an email on 09/08/2021 saying that my books would be delayed by a day so I would receive them on 09/10/2021, again no problem at all. I did not receive my books on the provided date (09/10/2021) and also noticed that on the Barnes & Noble website my order status said "Preparing to ship" on the date that I was supposed to receive the books. With that in mind, I contacted customer support on 09/11/2021 and was told that there were a lot of delays in the warehouse and that my order should be shipped soon, no other information was provided. On 09/16/2021 I received another email saying that my books had been delayed again and the new expected delivery date was on or around 09/20/2021. So with much frustration, I continued to wait and try to be patient. Then 09/20/2021 rolls around and I receive an email at 12:18 pm stating "We're sorry, we were unable to fulfill the below item(s) in your order, as they are not in stock." I am beyond the point of frustration because I feel that my books not being in stock was most likely known the first time my order was delayed. I was very excited to receive these books as they are a major tool for the career that I am pursuing, and it's very disappointing to wait for almost a month just to have my order canceled.
