They are charging credit cards for orders never ordered by the customers. They start small and than move to a larger amounts until you notice. I found 3 charges over a 5 day period ranging from $8 to $130. When you call them they say their systems are down and cannot take calls. I needed a book for homeschool in 2020 and had no choice due to shortages (Covid) of homeschool materials otherwise I would have never ordered from them and have NOT since.
