I logged on manually avoid the Facebook problems reported in other reviews, and had no problems in that regard. My t-shirt arrived about a week after my trip, and I was happy with the apps performance.
A quick hack though. The app uses location services, and although it says you need to be in the gift shop or visitors center of the distillery, you only need to get close, like in the parking lot. This was helpful, since we had leave early on a Sunday morning, but still needed three more stamps. We drove up before these distilleries opened, got our stamps, and drove off without getting out of the car.
Fun trip!
