This is listed as Price = $1.00. Just enter the amount you owe in the quantity box, & it will multiply that times $1.00/item. Round off to the dollar, because this computer is not smart enough to understand parts of an item. :> Example ( if you owe 319.46, you just enter 319 in the Qty box, & it will charge your card $319.00) We will write off the few cents difference.
