My experience on Bidcactus was basically consistent with the majority on here, but I'm not convinced that there are Bid Bots. Clearly it is gambling and clearly there are a handful of users (screen names) that win the majority of items. Yes they sometimes do pay outragious over-bids (bidding 240 times at $. 75 each time to win 100 bids back essentially paying $180 to win back $75). The question is, are there a handful of "PRO's" who drive up the price to intimidate others and reduce competition of future auction bids or is the site creating BidBots to defraud consumers. I did win some smaller auctions but ultimately flushed about $150 down the toilet (the majority of which was prior to spending several hours observing the action). I participated in appx. 10 different auctions and observed close to 100. I'd say about 10% of the auctions are driven to 2x and even 3x the actual value of the item however about 70% of the time, the winner of the auction appears to save about 50-60% from retail. I watched someone (presumably a real person) win an Apple Ipad today for $6.81 (which equals 681 bids of which no more than half could have been placed by the winner - conservatively 340 bids for a grand total of $261.81). In conclusion, if your willing to take a chance, do your homework! Observe the action, find out where the site is based out of, continue reading reviews, but keep an open mind.
