First of all, whenever I search GoDaddy auctions I immediately filter "expired" and "closeout" only. Any public auction is bound to be overpriced and/or garbage.
I used to be hooked on GoDaddy auctions, I'd find at least one good name under the radar every day that I'd end up reselling for way more than I bought it for. Those seemed to have long dried up as GoDaddy auctions have become more popular over the years. Nowadays, every time I find a good one, it catches the eye of a few others as well and always ends in a frustrating bidding war.
I rarely bother with GoDaddy auctions anymore unless I find a decent closeout that I can buy instantly. I don't mess with the auctions unless it's a name I really want, but again...the quality over the years has definitely taken a hit since more domainers buy and hold (or transfer out) all the good ones from GoDaddy.
