The Shop Disney Parks App currently has 25% off and free ground shipping on “most orders”. This is great if one of your favorite website contributors has a birthday coming up and you haven’t gotten her anything yet.
Seriously, though, I use the Shop Disney Parks App even when I’m at Disney World. It is sometimes cheaper (and almost always easier) to have items just shipped directly to my home than have to worry about transporting them myself back from Disney World. Since the app even gives you a lot of your various discounts (AP, DVC, etc…), it’s usually worth checking out.
