Im pretty sure they don't spay/neuter... shots, training, and grooming. However, bet they can refer you to a good and close place. PetSmart is a great place to help with all of your pet needs.
They have a Banfield vet office inside the store. Its possible they spay and neuter, but you should call yo find out. There are also organization locally who provide reduced costs vouchers for spay and neuter services and you can pick a vet from their list. One such organization is Be The Solution. I hope this helps.
The store does have a vet clinic inside it. Call for availability and price.
