Both times that I have ordered from BulkBooks.com I have experienced issues with shipping. I receive only a partial shipment while my account and the tracking number associated with the order indicate that the order is fulfilled and delivered. I have had to call customer support for both orders. This most recent order I called and got no answer. I never heard back from anyone until I called back again today and was told that the second half of my order should be shipping today. It seems there are some logistical issues with shipping and fulfillment at BulkBooks.com and I will be looking elsewhere for my next bulk book order.
