Another thought: feed sacks (the plastic ones) make good target bodies. I stuff them with shrink wrap that a local furniture store throws away, and use spray paint to make faces, dragons, or other animal silhouettes for my grandchildren. By suspending them from the top corners via cord or bungie cords between trees, off tree limbs, or from posts (or in the winter time from rafters in a barn), they last a long time due to the swing taking the energy out of the arrow. Easy arrow removal, very low cost, and the ability to make targets that grandchildren from four to eighteen enjoy make these a wonderful alternative for me.
Best of luck, Arch
