I haven't been on food stamps, as an adult. All of my examples are from childhood, when my mother was on them. There were no debit cards, then.
As I understand it, the debit cards are an option. They haven't phased out the actual coupons; at least I don't think they have.
I'm thinking a depot would be way more costly to the taxpayer. And once the unions organize the depot workers...it's over.
But usually, these are people in really bad financial straights. In my state, let's say a mother and child...they would have to have a GROSS monthly income of less than $1400 to qualify. So they probably couldn't afford transportation to the depot anyway, lol.
