Ebay advice, suspicious bidding?

[incoherent]

Yeah, thanks guys - sounds like I shouldn't expect much to happen here even if I report it. I'm fine with the end price but it's just the "coulda gotten a better deal" side of me that's nagging a bit

I suppose I could extend the seller the benefit of the doubt; maybe a legit newbie bidder randomly decided that bidding 2x the high bid might be a winning strategy and this is just how it happened to have panned out.

Good lesson to me to only last minute bid, or Buy It Now/Amazon/fixed price sales from now on.

I've never used Ebay but shouldn't a bidder's maximum bid be confidential between Ebay and themselves?

It was confidential until one bidder ran up the bid until my automatic overbids stopped, and then that person retracted their bid. Anyone looking at the bid history would be able to infer my max bid based on retracted bid's amount.
