Homestead Bonds are a means of funding Project Homestead. They are essentially gift certificates that can be redeemed at NuggetFest events and future Project Homestead events in exchange for food, patches, t-shirts, and more. After completing a purchase, a physical copy of your Homestead Bonds will be mailed out to your shipping address.The "value" represents the denomination on an individual Homestead Bond. So a $10 Homestead Bond is basically a $10 gift certificate that can go towards things like a NuggetFest t-shirt or Pork Roast dinner.
