A few of the stores will hold your purchases for you to come back and pick up. I've had hit and miss luck with that but it never hurts to ask. If a store won't hold it, I just come back at the end of the day and get it. I did use the service to send things back to the room but I tend to wait until the last day to buy things and you had to have at least two nights left on your stay to use it so I'm kind of used to coming back. I have seen it reported on a few sites that they will be starting back to at least sending things to the front of the park some time this year but that is not verified by Disney.
