in the recent past, I've booked rates through your great site via PriceLine, and after registering my bookings on your site, get no notifications of a lower rate,. But when I subsequently request a new rate for the same dates and times through your site as my rental gets closer, I get a lower rate. Example: Few days ago I booked a 2 day at SFO for $58, today I just sent a new request to you, and got a better rate of $41, same dates and times, was never notified of that rate. It's that auto notification once you register a booking at your site, that makes your site so special. I realize no one is perfect, but on rental requests over the past month or so, I'm not seeing the auto notification of lower rates that I have in the past.
