NOTE: Insurance can be setup as a minimum amount and a percentage of the merchandise sold. If the percentage is set to .01 (1%) and you sell $250 worth of merchandise, this will not exceed the minimum and instead will use $3.00 as the insurance amount. If you sell $450 worth of merchandise, this same setup will be $4.50 for insurance. Change these values in the setup as needed (this added in version 1.0.1).
