Spay/neuter coupons?

I don't know of any "coupons" although I do seem to remember going to a website that offered such a thing when we got Nigel. Also, there is a low cost clinic up in Hamilton county (lowcostclinc.org) that does reduced cost spay/neuter.

My brain isn't working properly so I can't remember all the details, but one month per year there are "coupons" available for a low cost spay/neuter at various vet clinics.

February maybe? I remember reading about it each year... but can't recall WHEN!!

Spay/Neuter Services of Indiana has an assistance program for lower-income households. They also have two reduced-fee spay/neuter campaigns they run (February and October) that are open to everyone. Here's the link to their info:
