I order a lot of books online, mostly used. My experience with BlueCloudBooks has been completely positive. On the rare occasions when there has been an issue with an order, their customer service department is on it like a duck on a june bug. They are professional, courteous, and always work to make sure I feel like a valuable customer. BlueCloudBooks is one of my go-to vendors for fair and honest used book purchases.
I understand people buy/sell used books. But sell a finished workbook? Really? The 5th grade workbook is mostly finished nicely by previous owner and there is little to resell it, unless the previous owner will have a change become famous. By the way, I ordered the book form Barns and Noble site. It turned out BlueCloudBooks.com is the actual seller.
