Getting the 30% off merchandise, even though I am no longer a member of DVC?

I am no longer a DVC member but I still have my blue card that is valid till the end of this year. I shouldn’t have any problems getting the 30% off of merchandise with my trip next month, right? As long as I present my card and ID.

Right.

But using it at meals that are table service might not work as they might actually “run” the card to see if it is valid? I could pay for all my meals with a gift card and not do a charge on my Magic Band, so would that make a difference or not?
