DO NOT TRUST!!!Likely scamming customers for nominal profits at a time. This business is as inefficient as it gets. DO NOT USE THIS COMPANY. I made the online order for a couple of books. I got quick automated responses after making the purchase. I wait for the order. It doesn’t arrive on time, so I attempted to do a shipping query to customer service. After emailing, and using the proper channels to contact customer service, I received a very lackadaisical response. The response was different then the first set of emails I received. It was plain text and indicated that the books I purchased where not available and that I needed to select different books at equal value. The verbiage was a bit odd and made me feel like I made an error attempting to purchase from this business. This made no sense, as I received email saying these books were on the way 12 days before that. There was an order number and again that response was automated, fancy, so at the time I felt like the purchase was legit. In my confusion, I explained the situation again and simply asking for a refund, if they sold me books they didn’t have. Still waiting for a response, a package, a refund or anything that makes this purchase worth it. DO NOT WASTE TIME OR MONEY WITH WORLD OF BOOKS
