I purposely paid extra to expedite shipping of a book. The two other books that I ordered on the same day have been received, BUT THIS SELLER STILL HAS NOT SHIPPED, he has sat on it since Friday morning, it is now after the work day on Wednesday - 4 entire business days and a weekend in between.THIS SELLER IS UNRESPONSIVE - it is sad that I have to go through means of a review because THE SELLER HAS NOT RESPONDED TO TWO EMAILS. Regardless of what shipping method, it is inexcusable, lazy, arrogant, and discourteous to not ship anything within at least a few days time.DO NOT USE THIS SELLER.
