haven't flown out of SFO for about a year, so was surprised at how much rates had increased. ParkSFO now prohibitive for longer than 4 nights stay.

Researched and found smartairportparking.com offers pretty competitive rates. Also, it has a name your own price feature. It had listed QuikPark at Aloft Hotel for $11/night. I was able to get this lot for $8.25/night when I named my own price. Receipt seems to show that tax is included - which saves an additional 10% or so. Nice deal.
