Why don't you guy's stop all of this auction nonsense and start selling fixed/store priced items and require immediate payment? I haven't had any issues since I started doing this.
The auctions seem to attract a lot of unnecessary. Unnecessary bidders who don't pay, who want to argue about prices/fees that they agreed to when they made their bids, non-paying bidders and etc.
You will still get people who are use to bartering (trade offers and regular offers), but that still coo', because you can say "yes" or "no" and adjust the price before hand. It really eliminates a lot of this. I'm sure that you @ cashflow are most likely facing account limitations at the rate that you're receiving bad DSR ratings. I highly suggest that you think about this. Their are other benefits to it as well, but I would rather talk to you about that via phone or PM.
I'm just saying...
