I have been using preferred for a couple of years now. Im moderately happy with the service. Sometimes its extremely fast, sometimes they are painfully slow. Sometimes they tell me a week and call the next day. Sometimes they meet a promise date but forget to call for 3-4 days. Pricing is fair. While they could improve, I am not unsatisfied enough to try to locate a new vendor that will probably have similar issues.

guy who answered the door was very rude. he lost my business because of it.
