We can send a replacement tube as soon as our order comes in, expected in a couple of days. Here in CA we often see customers with tiny leaks like this caused by a grass seed head called a goat head, that will leave a tiny thorn in the tread, and puncture the tube. Is the hole in your tube near the valve stem located on the outer surface of the tube? If so, you should check the inner surface of the tire, under the tread, to make sure that there is not a remaining thorn to puncture the new tube. I have also used a tube patch kit to repair such small holes rather easily.
