Cancelled my order because they said their system said my payment information was suspicious. It's the payment I use all the time so there was nothing suspicious. They cancelled it right away but still took my money so now they are holding up $150 of my money that I need to actually purchase a book. This company seems shady. No live chat, no phone number to call. You just have to sit and wait for them to return an email while they hold onto your money. I will never order from here again. I better get my money back.
