I take my calendars VERY seriously

Brian and I like having a Boston wall calendar in the kitchen. Every year, since 2003, we've had a particularly beautiful calendar from that city in our home. When we lived in Boston, it was easy to come across these calendars. In Arizona? Well, not so much.
So every year for the last five years, I've had to order the calendar from Barnes & Noble. B&N, usually, is right quick about getting books and calendars to the customer, or so that has been my experience. This year though, is bordering on the ridiculous.
Witness my frustration:
I ordered the calendar on the website on December 7. On December 10, I got an e-mail shipping confirmation, that the calendar was being shipped via ARGIX-USPS from New Jersey. It is now December 20, and I still don't have the calendar. The timeline, according to my "tracker": Calendar left New Jersey on Dec. 10; Arrived in Denver on Dec. 13; Left Denver on Dec. 14; Arrived in Phoenix on Dec. 20. Six days to get to Phoenix from Denver??!! What the hell??!!
I honestly believe that Barnes & Noble may be the only vendor employing the Pony Express this holiday season. Because this is crazy. Anyway, here's the e-mail I just sent to B&N's customer service department.

Good evening~
I'd like to lodge a complaint about your shipping service, ARGIX-USPS. I am having a real hard time understanding why a calendar that was shipped 10 days ago, according to the tracker, STILL has not arrived at my home. I understand that the United States Post Office also is involved in this particular shipping. The USPS can get an envelope from one side of the country to the other in three days. How is it that a shipping service AND the post office seem to be incapable of shipping a calendar from New Jersey to Phoenix in, at the least, 10 days?
The delay on getting this calendar is unacceptable.
As a website devoted to getting products to customers in a timely manner, as well as keeping them happy, you should be working with a more dependable and FASTER shipping service.

So, bets on the response I get? If any?
