Excellent free service, even better premium service!

I've won several items through placing a snipe with Gixen. It's never missed placing a last-moment bid.
As I'm a Premium subscriber (the mirror service pretty much ensures that your snipe will be placed), I've only once (in 5 years!) had a winning bid placed by mirror, but this one time made it worth the $6 / year. Bargain!
