I have successfully managed to spend the entire day using Apple Pay,
First I gotten gas by waving my phone over the reader. The bad part is that they don't have PayPass on the pump, you actually have to go inside, oh well.
Then I gotten groceries from Basha's, waved my phone over the reader, the people at Basha's didn't even know they had NFC until I waved my phone. The terminal has no mention of NFC on it whatsoever, but tap your phone and voila.
Then I got a Fanta from a Vending Machine, using Apple Pay.
Made a Walgreens stop as well. Looking good Apple, Looking good.
On launch day, I managed to pay to get a new Timing Belt from Big 'O tires, and surprise surprise, they had an NFC terminal, and I was even able to get my car fixed with Apple Pay.
