Yes! I printed my first one out and the girl behind the counter kept saying it was reading "denied". And didn't take it.
I'm hoping it's operator error and once they start getting more of these things, they'll know how to do it.
On a side note, a week ago I sent an email to the address listed on the site (
http://toystory3.kelloggs.com/faq) -- and never did get a response.
Hope this program gets the kinks worked out or Kelloggs is going to have a PR nightmare on their hands.
