Had the same issue with the same device. I received a notification from my credit card vendor for a large purchase for the first one, but wallet service hung up and wasn't even waiting for a response anymore, and the items weren't removed my cart so I made a second purchase, which showed up immediately in my orders. Half hour later I received two receipts, and a second showed up in my orders screen.

So, heads up if anyone made a similar mistake :) It's easy enough to cancel the order if you need to.
