About a week ago, I ordered a book from walmart.com. it was shipped (they said) with USPS. Now, one week later, it still isn't here even thought they said it would arrive between Monday and Wednesday of this week. When I use the USPS website tracking function I get this message: Service(s): Delivery Confirmation™ Status: Arrived Shipping Partner Facility Your item arrived at a shipping partner facility at 4:01 AM on April 12, 2010 in HEBRON, KY 41048. Information, if available, is updated periodically throughout the day. Please check again later. What does this mean? Will it arrive soon? 10 pts thanks
