I love 99c  and low start auctions.

As a buyer I have picked up some fantastic bargains  😄

As a seller I use them as loss leaders to increase traffic to my listings - I am happy if they do or don't sell at $1  as I am not expecting anymore than listing price.

Bonus is I get incredibly mixed outcomes from my $1 auctions, with several regularly selling for more than I had listed at buy-it-now.  Some of the auctions are fun to watch too -gotta love the nibble bidders :-x and I am particularly partial to bidding wars :-x:-x
