The listing fee for a $9.99 starting bid is $.40 and for a $10.00 starting bid the fee is $.60. Similar, but greater, differences take place at $24.99 vs $25.00, $49.99 vs $50.00, $199.99 vs $200.00 and $499.99 vs $500.00. Why do people list items with a starting bid of $10.00? I just don't see the logic in paying an extra $.20 in order to gain $.01. Anyone have any ideas why someone would do this? Maybe they don't think that ebay is making enough money. Just curious.
