To celebrate their new site, M&S is offering Times readers two-for-one on all cards.
What does the underlined part�two-for-one� mean in the ad?
A.Two paid cards and one free card.
B.One paid card and two free cards.
C. One paid card and one free card

Which one is the most suitable answer according to a native?

Thanks

I'd say it means C). One paid card and one free card.
i.e. Two cards for the price of 1 card.
Usually, the exact details can be found somewhere in the offer.
