Ethical question about food insecurity.

We are blessed to have enough. I came from hunger as a child so my thrifty self can’t help but drift to those Kroger markdowns. Staring at my $1.50 premade salad which is marked down from $4 because it expires today.

AITA for taking the discount when people are facing serious food insecurity and hunger?

Should I be tracking and donating the difference to the food bank?

Should I just abstain and pay full price for a while?

My conscience is not clear in this instance what is the right thing to do.
