It proposes replacing Fair Price Shops with a Food Stamp system, where beneficiaries receive coupons of a specified quantity of foods to purchase eligible items from private retailers.

Concerns like stamp perishability and inflation could be addressed through techniques like laminating stamps, bank redemption, and basing quantities not values.
