I loved the app on our trip last week. It would not hold a cart, so I had to buy items one at at time, and there were also the shipping costs to consider, but it was so nice to not have to worry about packing bigger things and to not have to stand in check out lines in the store. It has also been fun this week to have packages showing up at home about every day. As far as trying to wait until you get home, be aware that for many of the items, you have to be standing inside the store to purchase. There was one item I decided to order when I was back at the resort and it would not let me, I had to wait until I got back in a store that had it to order it. There are some things you can buy at home on the app, but not everything. It was also great when the store at Imagination was out of a Figment shirt in the size I needed, just jumped on the app in the store and was easily able to order it in the right size. We bought more than we would have without the app because we didn't say, oh that is too big to cart home and we don't want to mess with filling out the paperwork and time to have it shipped-a couple of clicks and it was on its way! I also did use it to locate an item a friend was looking for and it worked- but as fast as things sell at WDW, I could definitely see an item no longer being available where it indicated if you didn't get there close in time to checking the app. Loved it!
