One of the advantages to using the Swoopo single bid is that you can avoid the BBPW (Bid Butler Price War) situation. A Bid Butler Price War is when two bidders have Bid Butlers with the exact same price range and number of bids in their Bid Butlers. Swoopo rakes in the cash on these situations. What happens is that all of the Bid Butlers get added together automatically and the time gets incremented. All the single bidders sit back and watch you burn through your bids when this happens.
The risk you take with a single bid is from the time you click on the bid button to the time it registers on the Swoopo server may be too small. You see that there are 3 seconds left and click bid. Your computer sends the message to the Swoopo data center and to your surprise it says auction ended you lost. Huh?
This is because as your message traveled from your computer across the Internet to the Swoopo server it didn’t have enough time to complete the transaction. The Internet is a volatile place in terms of connections and how messages get transmitted back and forth. You just can’t guarantee with certainty that your message will get there in enough time.
It will however get there most of the time and we can use that strategy to help us force people using Bid Butlers to Burn through Bids.

With regards to the risk you take waiting, I’ve actually had it jump from 8 seconds to zero on my computer. (it’s not very good spec and my internet connect isn’t superfast either) I’d placed about 10 bids on the item as well! Not good strategy if your connection and hardware is poor!
