If it is a credit spread, that means you collected money when you established the position. When you close it, you will pay something--hopefully less than what you collected when you established the position. When you close a credit spread, you want to pay as little as possible.
Many traders place orders at the midpoint. Unless the stock is extremely volatile, you are not likely to get filled at the bid. You could try entering the order for a bit less than the midpoint, or a bit more than the bid. With the numbers you posted above, for example, you could try to close the position for a net debit of $2.98, or $3.02, or something like that.
How much of a credit did you get when you set up the position?
