Hi eddieras,
Thank you for using AuctionSniper. You do not need to be watching an item on ebay in order to snipe it. Most people use their watch list as a way to get the item into Sniper so they can place a snipe but all you truly need is the eBay item number, just as it sounds you used.
Please let us know if you have any further questions.
Happy Sniping,
Stephanie
