To clarify, yes, I ended my auction early even though one person had already bid. Yes, I was assessed a FVF fee of $8.77. I felt that was a small price to pay. I didn't want to be out both my Coach bag and the $50+ dollars I wouldn't be able to extract out of ebay unless I gave them my SSN.
By ending a listing which already had a bid, you end up paying the FVF based on the buyer's bid amount. So it didn't save you anything.
