Details, Details, Does Anyone But Me Notice or Care?

My latest obsession is card boxes. I am really wondering how much of a feature they are at weddings and how much anyone notices them. Is this a project worth spending time and money on? In my earliest musing about this detail, here are a few I have found around the Internet. All pictures and products were found on http://www.ebay.com/.

The card boxes I found ranged from traditional like this one....

To bird cages like many bees are using...

To a wedding cake shaped one like this...

To my personal favorite (though I am not sure I would pay $155+shipping for a card box)....This last one can be custom ordered in your wedding colors from eBay seller For the Modern Bride.

What will you do for your card box? Should I stress about mine?
