Sometimes you have no choice but to make a deposit. The first law school I heard back from was on ~January 8th, the deposit for that school was due on ~January 15th. It is refundable, but it is a hassle. I wish all schools had a consistant due date.
But as to the OP, out of the schools that you have been accepted too, narrow it down to one or two that you would most want to go to. You still have time to wait; you could wait comfortably until March 15th before sending out the deposit.
