Cost of living in general is much higher in New York than many other states (particularly southern states). I live in Texas and paid nearly $500 for 2 spays and I've heard $400+ more than once from people who live in your state. If you're trying to save some money, your best bet is to pick up the phone - call any shelters and rescues in your vicinity that deal with rabbits and ask if they can refer you to anyone who does lower-cost spay/neuter surgery for rabbits (most lower-cost programs are just for cats and dogs, so don't expect helpful results on your first phone call).
