From another website:
Just opened a Clear Sky Account today, Friday, Jan. 30th, to lock in the 3.75 and was advised via phone contact with a Chesapeake Bank rep handling Clear Sky that effective Monday, Feb. 2nd, the Clear Sky online rate will drop to 3.15. So you have through Sunday, Feb.1st, to open up and lock in the 3.75 until end of March when it will reset to ?, the new 3.15?
I can't confirm this, but it would be reasonable considering the rate cuts that have been going on.
For details about this savings account and Cleary Sky, please refer to my Clear Sky Account review.
