@KLJones1975 The key is you need to meet the driver, otherwise S/D will charge you a per pound handling rate. They've done this for some time. A while back one guest was pretty shocked by the bill.
The other factor is S/D doesn't have, to my knowledge, enough fridge space for groceries.
In my quick check Amazon PrimeNow was still an option to ship to S/D. On this webpage you will find the
Handling charges for package delivery, that is assuming you do not meet the driver.
IMHO this is where I see the Disney resorts going to as well. I'm not a fan of it, but I can understand it from a business perspective.
