Re: "Should eBay start charging non-paying bidders?"

Absolutely.  I'm a frequent buyer on here (spent well over $5,000 in the past few weeks alone on Ebay) so any on here who've even heard of me, would have done so in the course of me buying their item(s) as I've never sold a thing on here.

When I win an auction (or click 'Buy it Now')?  I pay IMMEDIATELY as that's only fair.  Other buyers should, too.
