It actually didn't give me an option to pay now, there was only the pay later option. Not sure why it did that. Oh well - I let it go. I decided $20 wasn't really worth the bother. That said, I recently made a Google Express purchase on the day it expired, and though it was pending for a couple days, it showed the charges as posting on the day the offer expired (though I still had to manually request the credit). So it seems a bit convoluted on their end.
