@tdebuys,
If you receive a DHL tracking number it is usually because the seller is actually located outside the U.S., in China or drop ships from there. For domestic shipping DHL is slower and more expensive to use.
The reason for the tracking not updating for a week is the time it takes for the item to come from China and to be processed through customs. Sometimes you can tell what service a seller uses to ship, by clicking on the Shipping returns and payments tab on the listing page. Most legit sellers will list the name of the service they use USPS, FedEx etc., in the shipping info on that page. Your seller did not.
You need to start checking each seller's feedback profile page before buying from them. You can click on the numbers of neutral and negative feedback the seller has received to read only those comments. Since neutrals do not count against a seller's percentage you need check those out. Never go by a seller's feedback percentage alone.
The last seller you bought from is Registered in China, as noted on their profile page. (Danger, Will Robinson) Their item location only gives the states their items are supposedly located in, all of which are known hubs used by chinese sellers. A proper item location has a city and state where an item is located.
