It really depends on the store... I never knew that 'hot' food was a no-no a couple years ago and we had bought some calzones for dinner on the EBT card and the store owner never said anything. Come to think of it, we had gotten pizza too when he had some really good deals.
I did see a Subway a few years ago advertising that they accepted EBT. I don't nkow if they do now or not.
I never heard of seeds being allowed, but if that is true that's very cool.
One store told me that ice was not allowed, but water was, yet I didn't have trouble buying ice with food stamps anywhere else.
I guess it just depends. i twould be nice if bulk food stores accepted them, because I know a lot of families use the bulk food stores because it saves them money and gives them the quantity of food they need in their house, and being stuck buying regulr sized stuff from the grocery store really wastes the governments money (well, for those who care to spend their money carefully! lol). then again, you can use coupons which can make some deals better than bulk too.
