Connecticut's dealer figures come from the prices local delivery dealers post publicly, gathered every morning from third-party listings. Each dealer counts once, at its most recent price posted in the last 14 days, so a dealer that serves several areas doesn't tilt the average.
The state survey line is the statewide residential average from a weekly government price survey, collected from October through March.
Posted prices are what dealers list publicly. Delivery minimums, payment terms and service areas vary, so confirm the price with the dealer before ordering.
