Non Payers!!!

I Know, I know, we have all had non payers and people who "will pay" but I seem to be having more non payers or problems with buyers this past year than I have had in years - and I have had an eBay account since the late 90s, (with a different user name) And repeat non payers!!! How on earth do the get away with it?  I have since blocked a few non payers but there needs to be something else done to protect the sellers on eBay from thse time wasters. EBay reasons that it changed the rules on negative feedback from buyers to sellers to increase buyers therefore increasing postential sales - GREAT we just need them to pay up! I have missed several sales now due to non payers and by the time the 4 days, contact buyer deal is done, then the 8 day to pay time waster is through, buyers have gone elsewhere. Appologies for repeating the obvious but I needed to vent. Thanks for "listening" Cheers, Dave
