I dispose of (recycle) most of my boxes and cardbacks. However I 'clip and save' any tech-specs or equivalent (have done since 1985). I also keep packaging in the following instances:

- Toys I have purchased but am still deciding if I want them or would rather give them to a friend stay unopened.

- Big toys like citadels or gestalt sets are too big to fit in my storage draws so stay in-box while not on display. Packaging also enhances how impressive these toys can be.

- Sometimes a particularly nifty or interesting box is preserved. I also recently decided to keep a sample of packaging for each size class.
