Hi rusty420 -
That is correct - using an amount that is not a whole number is helpful when placing your bids, so the amount you note would be a good bid price.
We do not recommend lead times less than 5 seconds for optimal snipe placement, but the site will allow you to set a lead time as low as 2 seconds.
Bid Enhancement is optional and may increase the price of your bid beyond your Max Bid (please see the Help window for Bid Enhancement, the "?" in that area of the My Snipes page). Please be sure you understand eBay bid increments prior to applying bid enhancement to your snipes.
If you have specific questions about any of these or other features of the site, please feel free to file a support case from under the Help tab of the site and we'll be happy to continue assisting you.
