Some might be misled with total calculator of Turbo Lister program during the eBay listing discount actions. Turbo Lister calculator estimates the pre-listed items listing total charge to be as always and not showing up any lower totals during different eBay listing discount events. However it does not mean that listing of  items via Turbo Lister would cause the larger charges in fact,all discount appear as promised and can be seen at My Seller Account Summary details.
