We’re in New York this week and decided to stop into one of the Costco locations yesterday because it was right next door to something else we were doing. And while we were there I remembered the question about Costco cake designs, so I tried to get some pictures that I hope will help. This is probably too late to help Julie (the commenter looking for pictures), but maybe someone else can benefit from it. Also, I picked up an updated cake order form (for the US), but I will have to wait until I can scan that to get it posted.
I’m guessing that the ‘Flag’ and ‘Graduation’ cakes are seasonal but all of the others I believe they do year round. And I apologize for the lackluster photos but all I had with me was my iPhone because I wasn’t expecting to go to Costco (yes, I always shop with my camera….just in case). If you click on the images you can see the full sized photos which are pretty decent sized and should provide enough detail to get a decent idea of what the cake looks like.
