Since this code just expired, was looking for a new one. Found this in the comments of an older deal, credits to @Crownanchor.
Couldn't find information on the expiry, but the T&C should be similar to other deals, so copying and pasting the relevant bits.

I received 3 x 50YUM codes on 2 different occasions last week through doordash emails. The code doesn't work with any provider, it will say something to the effect of "not available at this location" - has anyone come across this or know why the code isn't redeemable?
