during testing, I couldn't place the bid amount I wanted. The plugin would change the amount. Say I wanted to bid $10. on an auction and the previous bid was $5.00. Well, this plugin changes my bid to $6.50 or some other amount that seems completely random. This could be a little (or a lot!) confusing to people who want to bid on an item.
I went to their support site and saw someone else posted this problem. Their reply was that is how all auction sites work. But when I use ebay, If I bid $10., my bid is $10.
