Horrible experience. Ordered an Advanced Review Praxis book and paid $18.00 extra for two-day shipping on a Friday. Called the company today (Tuesday) to find out where my book was only to find out my order had not even been processed! They told me I wouldn't get my book until Friday AFTER they charged me for two-day AGAIN! Told them to flat out cancel my order. AWFUL customer service.
