Well, if we go with figurines, then I don't think we should order all companions, because we are Cullenites! There should be Cullens!

Calculating the costs is kind of difficult for me: in Russia we just say how many kilograms a cake must be, not how long, lol. For example, if we talk about 100 people, then the cake should be 10 kg. Or two cakes 5 kg each. Rectangular or square, not sculptured, decorated with either printed fan art, or with figurines and a thank you message written manually. I have no idea what the tastes should be, because I only eat cheesecake myself

Anyway, we need to find out how big they can make a cake, and what will be cheaper - one huge cake, or two big cakes. Maybe we shouldn't aim to feed everybody with the cake, especially if we add cookies, then maybe it's better to order one 5 kg cake and cookies? Candace site says it's 7 dollars per serving for a cake, so that would be 700 for 100 people, that would be 26 dollars from each Cullenite, and we know that not everyone can afford that. Plus cookies and delivery. I don't know how much the cookies would cost, but if we want to decorate them with sword's of mercy, that would be 100 dollars for just decorations. So I guess to feed everyone we need at least 1000 dollars, right? 37 per Cullenite.
However our goal is not to feed the hungry, it's to show our love. So maybe one 5-6 kg cake without cookies, plus a thank you card signed by Cullenites would be our best option? 5 kg cake is big enough for everyone to taste, I'm sure BioWare team will share with each other. Let's just be realistic about our goals.

Then there is a chance 350-400 dollars will be enough, that's 15 per Cullenite. Some of us can spare less, but some can chip in more, and it will probably cover that.
Now it would be nice if somebody could call to Candace and ask how much would every option be:
5-6 kg cake with 3 marzipan Cullen figurines on top
5-6 kg cake with a custom printed image on top, and the image requirements.
150 cookies with a sword of mercy on them.
And how much is the delivery.
