Known as the “BASIC Act,” the bill from Sen. Josh Becker, D-Menlo Park, would require items sold at prison commissaries or “canteen” stores to be marked up no more than 10% above the price paid to the seller allowed – a steep price reduction in current prices, which are often 65% higher than the provider’s price and can reach markups of up to 200%.
