Hi Snow,
On “My Watches” page, click on “Watch Preferences”. There’s a “Auto delete watch” preference. The only problem, whether that’s checked or not, the auction is deleted from the watch page when added to the snipe list. You might want to file a support request (sounds like a bug, or I’m missing something):
http://support.auctionsniper.com/Also, I couldn’t get a comment on the Watch page to transfer to the snipe page. May be another bug, or another I'm missing something.
