Thanks TW,

Those are great ideas!

I like the idea of the card caddie... I hadn't seen that before...

And the 16 Pocket wall Locking Business Card Display is pretty excellent, too. Especially with the "locking mechanism" to stop people putting in their cards without permission.

I can think that a lot of stores would find these particularly valuable...

Thanks for finding these and posting about them! :)

Best wishes,
