Drugstore.com also sells and ships it. If you are a Shoprunner member it is free 2 day delivery with minimum $25 order.
As others have noted, Amazon also sells and ships it (sold by and ships from Amazon). Amazon Prime will get you 2 day delivery or, with a small fee, one day delivery, if desired.
On our last several WDW trips I have used both Drugstore.com and Amazon to order things and have them delivered to our resort. IIRC each time we have been staying at Wilderness Lodge; since it is not a convention resort there was no charge for receiving the packages. What I do is confirm they have been delivered through the website's tacking, and then when we arrive (or if ordering during the stay), go to the front desk to pick them up.
If I am getting them for arrival, I place the order so it arrives a day or two before we do (Shoprunner and Amazon Prime are helpful in this regard); 2 or even 3 is good since it gives a buffer for delays... When we arrive and check in we go and check out our room first and make sure there are no issues, then I head down to Bell Services to have our luggage sent up to the room; at that point I also tell them about our Garden Grocer and any shipped orders so they can retrieve them as well and bring everything up at once. We tip accordingly for the total # of items delivered to the room.
