Just got back from our Thanksgiving visit with my mom, so I'm late to the discussion.
The cookies are in all of the candy shops and are so, so, so yummy!!!! It's why I bought 3 of the gingerbread kits with the Mickey gingerbread man cookie cutter. They are a bargain (to me) at $7 plus you presently get the AP discount if you're a pass holder. I also bought the Mickey head cookie cutter, but I love the little gingerbread mickey one and it's only sold as part of a kit that includes the gingerbread mix. The kits are also in all of the candy shops EXCEPT the one on Main St., or at least that was the case the weekend before Thanksgiving. The Market House had them but the candy place did not. I also saw them in World of Disney and the gift shop in DLH, but not at GCH. Can you tell I scoped this out?!
I just wanted to mention that I asked while I was at DL (Pooh Corner candy shop, to be exact) if they could ship them for me and was also told no. They are not allowed to ship any food items because if the recipient is not happy with it they are required to replace it or something along those lines. I didn't pay too much attention to the explanation once the CM told me "no."

It's just policy and one of those things you can't get too upset about. It would be nice, though, if they would offer more cookie cutters without attaching them to other items, especially food items! Last year I wanted the gingerbread man but didn't want the whole apron kit or whatever it was. At least you could ship that, but it would be nicer from a consumer standpoint to be able to just buy the cookie cutters alone. I'd love to have a set of MM cookie cutters in various sizes. I love the gingerbread mix but hadn't thought about the shipping aspect.
Anyway, the site someone posted mentions that she only has 12 of the kits, so if you want one you probably ought to buy it quickly. That person is charging double what they cost at the parks but the only other option I can think of is to see if someone who is going to be in the parks would get one for you, which would mean that person would have to ship it to you etc. so that would probably have to be a last resort.
