I usually look a couple times a week to rebook a rental car in case the prices go down, and they usually do at least twice (one time I rebooked six times and went from $212 to $88). But yesterday the price changed three times in about a six hour span at Payless and Advantage. Is this normal, that much change that quickly? I hope they do. I'm at $111 for a compact now but looking to get down into double digits.
