It used to be that when you changed your bid price up or down the change only took a few minutes. Now if you decrease your bid, the change doesn't seem to happen until the next day. It's happened to me twice in the last 10 days. I decreased a bid at 6:15 am according to google's history in the tools section. The average price hasn't blinked. 12000 clicks later, it's still at the old price. Same problem last week. The bid didn't change until the following day. Technical issue or yet another unannounced money grab?
