Let me give the company answer...
Has the profit on sales gone up? I don't think so.
Is the increased cost of gas only effecting the rep? Quite the opposite. The Dealer not only has increased costs of gas but everything associated such as freight. Freight costs here have doubled and now Ricoh doesn't pay the freight on DMAP orders so that is a double wammy.
You might want to be careful what you ask for. You might get the company looking at gas expense and deciding they can't afford to pay reps anything anymore.
