At Amazon, get up to a $30 mail-in rebate ($15 for front, $15 for rear) when you purchase select Wagner ThermoQuiet Brake Pads. Plus, Prime members get free shipping. (Non-members can get free shipping with pre-rebate orders of $25 or more; otherwise, shipping starts at $8.53.) With deals starting at $14.66 after rebate, many pads are at the lowest total price we could find. (We saw the same discount with up to an added $20 off with pro installation about a year ago.) Rebate ends May 31.
