There's a date by which you have to enter (Friday I think) to allow time for all the winners to enter their addresses. Once that date has expired then Anker in one event go into that Google docs form and then initiate the shipping.
You may get a shipping notification next week. They use Amazon's shipping partner from my experience using the cheapest shipping so ~ 3 days for example here in California.
Assume 2 weeks from competition win til in your hands.
