I've been a member of Bidwiz for 3 months now, I don't recall exactly how many auctions I took part in but so far I've won 5 items at a total worth of about £800 for £59 a month.
Seriously, it's worth it. So far I've gotten 4 out of the 5 but the last one was pretty recent so I believe I'll be getting it within the next week or so.
Will update if not,
