I'm not seeing why this is complicated. Disney bell services will deliver luggage to the room complimentary. They will accept grocery deliveries, store them, and will bring those groceries to the room for a $6 fee. They don't charge to store the groceries. They just charge a few dollars to bring them to the room. It's been that way for awhile now, and the $6 has saved us a lot of elbow grease some trips. A lot of families have a lot of groceries delivered some trips because of the make up of the DVC rooms. If you don't want to pay $6 as part of the trip, then just go pick them up at bell and take them to the room. Whenever possible, we have the luggage and groceries brought up together, and then tip on that - not specifically the grocery delivery. But the bell person gets a nice tip bringing all that stuff up for us!!
