Walmart has the Office Impressions 1″ Round Ring Economy Vinyl View Binder 3-Pack for just $7.44! (regularly $10.50) That is just $2.48 per binder! These are great to have on hand during the school year. You never know when a class project is going to require one, or when one will wear out and need to be replaced.
Be sure to select free in-store pickup to avoid shipping fees. Otherwise orders of $50 or more will ship free.
