I have dealt with this site previously, and had no problems. However, I sent a package of 4 books back in February and have yet to receive payment. Also, I emailed the company FIVE times since March and NEVER got a response. Since the service was great before, I sent the package without delivery confirmation. I'm so mad. Any type of communication would be helpful, but they refuse to respond at all. I won't be using this service ever again.
