I Just got a unexpected tracking number for 2 Typhoon H batteries I preordered form Adorama about a month ago. I think they we're a $83.00 per battery pre-order special that we're back ordered week after week. I was days away from canceling my order. I ordered 2. They will be arriving on my days off. Now I won't feel pressured or rushed. I have three batteries to develop my skills. What a stroke of luck.
