What are delivery charges for online orders? Is there any free delivery in Manhattan with a minimum order of a certain amount?

I don't know. U have to go to their web to find out

I haven't used their online shopping service, I usually shop person. But to answer your question it's to call a store representative just to make sure.

Costco has no delivery till I know, you can make orders and pickup thereafter this is only service they offer by now.

Or call the store.
