I suppose they chose that form to reduce the shame factor for those people who rely on food aid to get through the month. Secondly, the range of items you can buy is pretty broad. Check it out:
What you can buy with food stamps [7 C.F.R. § 271.2]
--- Any food for human consumption except hot food (but remember, there is also an exception for approved restaurant meals programs).
--- Seeds and plants to grow food for yourself or your family.
What you cannot buy [7 C.F.R. § 271.2]
--- Pet food.
--- Non-food items such as soap, toothpaste, toilet paper, cigarettes, etc.
--- Vitamins and medicines.
--- Any hot food, including hot food intended for immediate consumption (with the exception of restaurant meals programs).
Interesting, right? I actually found out that Papa Murphy's Take & Bake Pizza accepts EBT cards. Considering that it's around $6-8 per pizza, and that is a meal that feeds my family, I think it's not a bad deal. Not for regular use, of course, but pretty neat. Anyway, hopefully it doesn't come down to that. But if it does, I'll know how to use it!
