US President Donald Trump has given small businesses a 90-day extension to switch to new rules for the SNAP food assistance program, Fox Business reports. Previously, the USDA required stores to stock at least seven types of products in four categories, including dairy, meat, vegetables and fruit. The November 4 deadline threatened to exclude from the program tens of thousands of small retail stores across the country, for which payments on coupons can account for up to 30% of revenues.
