One must be a Costco member to place an order online. To my knowledge, Costco does not offer pick-up in store for orders placed online.
You can log into their website if you are a member. All items and more are available. Returns can be brought to the store.
You can order online and if in store, you can order cakes.... you can call them on your phone too and order...perishables aren't sold online though...
