eBay is once again offering some reduced listing fees for sellers today only.  There are some qualifications though,

On April 21, 2009, sellers who list Auction-style item(s) and have a 12 month Detailed Seller Rating of 4.5 or higher on all criteria, will pay just 15¢ Insertion Fees per item listed. New sellers who don’t yet have DSR ratings are also eligible. DSR rating criteria for this promotion will be based on the previous 12 months. To see your DSR ratings, go to your Seller Dashboard within My eBay. For more information on DSRs, click here.

Starting Tuesday, April 21, 2009 between 00:00:01 PT (12:00 AM plus one second on Tuesday, April 21, 2009) and ending that same day at 23:59:59 PT (11:59 PM plus 59 seconds). * For listings on www.ebay.ca, the promotion will begin at 12:00 AM plus one second on Tuesday, April 21, 2009 ET and end at 11:59 PM plus 59 seconds ET.

This could potentially save you $3.85 per listing.  For a full list of the fee savings and what items are excluded (as it is a lengthy list), click here.
