Where I live (San Antonio,TX):
The Animal Defense League is doing spay/neutering for 10 dollars.
The Animal Care Services has days where neutering is only 5 or 10 cents.
The Feral Cat Coalition here gives vouchers that take 10 dollars or so off a spay/neuter, I'm not sure if the FCC in other areas does that.
Edit: All will spay/neuter ferals, Humane Society of Bexar County will as well.
