We were also within days of a trip last fall when the September pricing increases occurred. Speaking from experience, I can offer one bit of advise. When Disney does announce price increases, most of the Internet ticket brokers are able to hold the old prices for a week or two as their inventory dictates.
We purchased from Florida Orlando Tickets just as the price increases were announced. I followed their web site for at least two weeks as they proclaimed "get them now before prices go up."
