I had mixed results with the App. Used it last month in the parks. Fun! It was helpful finding where things were being sold in the parks. Took a long time to open and load, but not sure if that was my connection or not. I was in the parks, so on WiFi, but still got spotty coverage.
So I shopped and loaded several item I saw in my cart. After all, free shipping and saving space in the luggage, right? So I got home and tried to make my purchase. Error. Tried again. Error. Called two or three times and finally got through to someone who told me it won't recognize a PO Box for the billing address. Seriously. Said they were "working on it". Me: 'so what do I do?" Them: "call this number and place your order through them". Okaaaay.
So I called, got a nice lady, but had to literally go back to my phone app shopping cart and write down all the SKU numbers so I could read them off to her. I had 14 items! So about 1/2 later (nice lady, but she had to look everything up one by one), my order is placed. This was December 22.
I got a phone message this past Monday saying one of the items I had ordered was now out of stock. Really. I walked past that item every day in the parks and didn't pick it up, thinking I've got it in my cart so I should be good. Even when I got home on the 22nd, still thought "I've got it ordered, should be good. It was IN stock when I ordered it. NOW, it's out of stock (it was a Christmas item).
So, mixed results. Left me a bit disappointed. If you have a PO box for your credit card billing (because, like, who doesn't now with mail theft everywhere), beware.
