No. But you should expect (I think?) the grocery store not to ban the cookie maker from packing notes about how to order from the maker directly. (Edit: I mentioned that because, per the story, I think Apple has a policy of prohibiting you from telling users how to circumvent Apple's cut.)
I actually don't know if grocery stores generally require this -- maybe they do. I suspect it's not an issue because it's generally going to be more expensive to do one-off orders directly from the OEM, unless it's an order too large for the grocery store to want to manage anyway.
