Since the EBT initiative in farmer’s markets, in which shoppers can choose to pay with their food stamps, not only have EBT sales gone up, but more and more markets are accepting EBT! In fact, in 2005, there were 3 markets, and 23 in 2009! In that time, EBT sales have increased one hundredfold to over $100,000 annually, and in some markets, daily EBT sales have topped $3,000.
