It sounds like Expedia will claim this was a pricing mistake.
The challenge is that it's not possible to tell at booking-time whether an 0.01 fare is a mistake or not. As we all know, airlines/hotels frequently do this intentionally, so you just book one and hope it is later decided that the fare is legit.
