Can you order a custom decorated cake from the Costco in Lacey?

I believe you can. Best thing to do is give them a call and ask the bakery department.

Yes they can, but it's always best to ask if they can do something special

Custom to a point. They have a book you can look through... make a selection from there. But they will personalize it for you. Name. Phrases.

Yes

They do only the cakes on their cake list for copywrite reasons
