It is currently #3 on Amazon.
Buy the book from Amazon and send a copy of your receipt to Costco and Costco’s board.
The board should be approached by stock holders as to why they allowed left wingers to eliminate a best seller from the books they sold.
It is currently #3 on Amazon. So if it isn’t selling at Costco, it was not on the shelves. It would not be the first time the left wingers in control of Costo didn’t sell a conservative book.
