The shelf life of anti venom stored properly is 2-5 years depending on the manufacturer. A good veterinary practice will have little trouble writing off the cost of any that were unused.
It is a cost of doing business, what we don't use in our hospital pharmacy is replaced. A good Vet practice in snake country would do the same.
Last visit for two Dogs, shots and examination was around $500. Six Dogs buys a vial of antivenin.
