How can you ensure you hit the shipping minimum? Collect them from friends who play guitar, bass, or orchestral instruments, and ask bandmates, classmates, etc.
Increasing the weight limits reduces the carbon footprint of transporting waste, which helps to ensure maximum efficiency and effectiveness of the Playback program. Thank you for supporting our efforts for a cleaner planet!
