It's okay that you don't know where Idaho is. You, after all, live in North Carolina...why should you bother to know where all the other insignificant states are, especially those distant and comparatively sparsely-populated western ones? However, after I explain to you where Idaho is ("between WASHINGTON and MONTANA"), and give you a very simple address (which you read back to me flawlessly over the phone), it is NOT EVER acceptable to send my badly-needed replacement centrifuge lids to Tennessee.
P.S. It is also very illegal to promise on your website that you will respond to my email within two business days, and then send me a casual and useless reply proving that you never even READ my email three weeks after the fact. BAD BIOENGINEERING CORPORATION. NO BISCUIT.
