I love the concept of this company, but the deliveries left something to be desired. The first one had been put into the shipping envelope so that the book cover was stuck to the envelope glue. Couldn't remove it without teartng the book cover. The second shipment came with $11 COD when they claim free shipping. Don't mind paying for shipping, but having to go to the post office in the midst of COVID19 lockdown was not appreciated. If I'm going to pay for shipping it's much easier to take care of it at the time of purchase.
