eBay is offering a 10cent Listing Special when you convert a store listing to either an auction-style or fixed priced listing.  Here are the details:
 
As a special offer to our eBay Stores sellers on www.ebay.com and www.ebay.ca, we are holding a two-day promotion where your insertion fees will only be 10¢ when you move an item from Store Inventory format to auction-style or Fixed Price. In addition, you’ll also get free Gallery on these listings.

The promotion starts on Tuesday, August 15, 2006 at 00:00:01 PT (12:00 AM plus one second) and ends on Wednesday, August 16, 2006 at 23:59:59 PT (11:59 PM plus 59 seconds). Please Note: the reduced fees for this promotion will not be immediately reflected on the site. Sellers will receive a credit to their account in September.

The 10¢ Insertion Fee promotion will not apply to eBay Motors vehicles and Parts & Accessories listings, or to International, Live Auction, Professional Services, or Real Estate/Ad Format listings.
