I think they are standard and only customize by the writing, as in "Happy Birthday X".

Pretty sure they will only do their standard designs. You don't even talk to anyone when you order, just fill out their form.

The cakes I have ordered have been all standard but they will do different colors or mix some elements up if you ask. I got help from a baker in how to complete their standard order form for a semi custom cake

I don't know about Costco, but I would call and ask them. Several years ago I brought a photo once to Sam's Club and they were able to copy it onto the cake. Actually, it was a picture I printed from my computer (not a photo, but a cartoony type of picture I found online). Actually, I may have also done it with a photo. Either way, I would call Costco - seems like if Sams could do it, perhaps Costco could too. It was like they photocopied the picture onto the frosting somehow - it turned out very well considering the method.

Thanks all.........I was pretty sure they just did their generic designs and would only add a name. I remember when you could order a cake online....I don't know why they took that feature away. As far as I can tell they don't have any info at all about their occasion cakes online..no pictures, prices, etc..which also does not make sense to me.

Jooanie5, Costco.com and Costco are actually two different entities so there are often items in the store that are not available on the web site and vice-versa.
