So does anything cost a penny anymore?

I can't find anything that costs a penny.  Amazon has a few things, like cheap earrings and necklaces or stuff no body in their right mind would ever purchase, but the shipping is usually $5 or more, and all of them are from the Amazon marketplace (sold on amazon.com by other vendors).  There is nothing directly from Amazon that costs a penny that I could see.   Wal-Mart and other online retailers don't have anything for a penny that I could find.  But seriously, if anything is listed at a price point of $0.01 then it's probably grossly overpriced. We round now. Why don't we round a little more and get rid of those pennies?
