Amazing $8.01

The biggest argument I've heard against scrapping the penney is that such a move would cost the American consumer by "rounding up" the cost of nearly every item sold. Or would cost American businesses by rounding down. If sales tax is 7%, a $0.99 item comes out to $1.06 total. So either the consumer pays $1.05, and the business or state "eats" the penney (losing revenue) or the consumer pay's $1.10, effectively resulting in a 4% inflation of the item's price. Of course, with more expensive items, the rounding factor diminishes the percent difference.

I don't know if any of this is necessarily a "bad" thing, or if it's just an argument against change.
