I watch items all the time.  Has nothing to do with them being .99. 

About four years ago, I bought two items for a total of $60.00.  Recently I saw a similar item that was sold for a lot more than I paid.  Not being sentimentally attached to the items, I decided to sell mine.  Received a total of $145.00.  If I hadn't been watching the item I was, I wouldn't have decided to sell my items.

Instead of accusing people of wanting something for nothing, look at other reasons why people may watch items.
