I'd forgotten about that. Technically, you've got me I guess...let me amend that to "I've never
asked a seller to end an auction early".
I wasn't particularly worried about security, given that they were low-priced items, coming from a forum member, and I was getting an item in the same batch via eBay where I could give negative if need be.
I also wasn't very concerned about fairness to other buyers, since there were no bidders yet and they were not highly-collectible+rare items by any stretch.
The part about eBay's cut never even occured to me at the time, since the seller always handles it, and I haven't ever sold anything.
