What still costs a penny? I can't think of anything. I think it is time to retire the penny. Obviously stores might object because they can't do their $4.99 sale instead of $5.00. But if they were allowed to round off at check out, they could still have items throughout the store at $0.53, $7.84, etc. and the most difference it would make is $0.03. After all, some gas stations still do that 9/10 thing. It has cost more than a cent to make a penny for some time now due to material and labor costs. Why do we still have them just filling up jars in every house across the country? When you leave to go shopping, do you make sure to grab your pennies? So is it still just a "penny for your thoughts?", or do your thoughts cost more now?
