These are great suggestions for card savers. Just a thought about shipping in 8 or 9 pocket pages. Go to your local pizza resraunt (shameless plug) and see if you can get a new 14" box. Fold the box the way they would only inside out. The pages fit perfect without much wiggle room. You can fill around the edges with crumpled newspaper. If only pages and not in a binder I would suggest putting a zip tie in the page holes to keep them uniform. The box is sturdy and it's always fun getting a delivery, pizza or otherwise.
