I never really paid much mind to these ads. These weren't exactly all that memorable but I suppose there were way worse :30 adverts out there. However I have to admit that I was legitimately surprised by the most recent one:
Every other so far has been presented as visual representations of Discover treating the customer like the customer would themselves, but here it turns out they are literally twins. I did not see that coming. Although now that I think about it, shouldn't the sister who was working for Discover have figured out that she was talking to her twin when she pulled up her customer information?
