That is a "buy it now or best offer" sale, something relatively new that is not an auction.
Yes, watch shipping, sometimes the money is made in crazy shipping costs, so look at the entire deal. I have paid $30 shipping on a $10 winning bid, and thought it fair (65# blacksmith's post vice, arrived in a plywood box). I have also bought stuff that ended with $30 shipping arriving in a flat rate postal box for $11 with advertizing as packing...
