not many people do based on the fact the price is rounded. If the price ends in 1 or 2 it goes down of it ends in 3 or 4 it goes up. And who cares why waste your time posting this. We do not use pennies anymore however we do still accept them. By law the stores have to take half pennies we don't use those anymore ore make them but a store would have to take it as it is legal tender. please note that you would be silly to use a half penny as it would have a greater collector value. If you are going to comment please get your facts straight please,
