I was thinking what a good idea it would be if geocaching/Groundspeak would allow you to purchase a travel bug number at a discount and print it out instead of having to buy the dog tag and wait for it to be shipped.
Of course the Geocachers would need to laminate it but I don't think that would be an issue. This would save time and money I think for both ground speak and the Geocachers.
Just my 2 cents.
