Locally if at all possible. I can find them online, but not at any websites that I'm familiar with and, therefore, comfortable buying from. I didn't even think about purchasing on at WDW (duh!).
Actually, you know what....I was really thinking it would be cool to make Mickey waffles in our DVC, but I didn't want to take one with me & then bring it back. But, if I bought it there, I would only be packing it one way! Hmmm...the question now is, can I wait 6 more months for it?
