One month prior mI ordered a book through Amazon on Infinite Books, was told the delivery would be April 21, 2020, Amazon says 'shipped' but I have not gotten it, contacted Infinite Books, they send me a general letter to contact the carrier. I cannot track this delivery as I do not know which carrier they used. Very strange way by Amazon to state that. Not sure how Infinite is sending out their books, but just put it in an envelope would have been sufficient to send it even during Corona virus time. I live in a safe area and never had problems getting my stuff through Amazon
